Gibberish of Love

"Calvin: What's it like to fall in love? Hobbes: Well...say the object of your affection walks by...First your heart falls into your stomach and splashes your innards. All the moisture makes you sweat profusely. This condensation shorts the circuits to your brain, and you get all woozy. When your brain burns out altogether, your mouth disengages and you babble like a cretin until she leaves."

- Calvin and Hobbes

Bob sits at a booth in a pub, looking around. Everyone seems to have someone to talk to, and he spots Alice at the bar. Putting on his best smile, he heads over, desperate to just make some conversation.

And then Alice turns around. The screen goes soft and hazy, the romantic music starts up. Bob is amazed, and realizes that this may well be the single most momentous thing to happen in his life. He imagines minivans. He imagines children. Even a little white picket fence.

Bob opens his mouth and says a romantic "Lemons are very nice, especially in the summertime."

He has been struck by gibberish of love. Sometimes caused by Distracted by the Sexy or a Hello, Nurse!, it doesn't even have to be a sentence using words—plain noises work just as well. Occassionally happens if Twice Shy style love interests attempt conversation.

When the gibberish is coherent, but unfortunate, they're often Digging Themselves Deeper afterward. Usually male, and often happens to Adorkable characters. Sometimes immediately lampshaded with something along the lines of "X...smooth...". May be a habit of the Shrinking Violet.

Compare Love Makes You Dumb and Love Makes You Crazy. Compare and contrast Angrish. See also I Uh You Too (for when the relationship's evolved a bit before the gibberish), Cannot Spit It Out, and Crush Blush.

 * In Hakaima Sadamitsu, the gang once runs into a Kamishiro wearing only underwear (she was chasing an Exile that stole her top and lost her skirt when she jumped off the roof after the creature). As they're being Distracted by the Sexy, one of them squeals "Meet to nice you..."

Film
"Lloyd: I desperately want to make love to a schoolboy."
 * In An American Tail, Tony Toponi is reduced to staring and jibbering when he first meets Bridget. She fares little better, reduced to giggling and repeating the word "cats" until Fievel causes their Accidental Kiss.
 * In A Goofy Movie, Max mostly jibbers and stammers when he first meets Roxanne, and is very concerned about keeping a good image...and then comes the fatal "Huh--YUK".
 * In Dumb and Dumber, when he finally has a moment alone with the woman he's been chasing for the entire movie, Lloyd rehearses a long speech about being giddy as a schoolboy and desperately wanting to make love to her.


 * In Mulan, Shang acts like this, more than once, after he learns that Mulan is female.
 * "I'm in lesbians with you."

Literature

 * Harry Potter and the Goblet of Fire:Harry asking Cho to the Yule Ball comes out as "Wangobawimme?" (I paraphrase)

Live Action TV
"Girls: We are Norma. We are a hair artiste. Goodies: We are Cyril. We are a bank clerk. Girls: That's interesting. (Beat) Girls: [awkwardly] Our vision is to own our own hair dressing salon. Goodies: How interesting. Our ambition is to own our own bank."
 * The first time The Goodies meet their dancing partners in the episode "Come Dancing", this ensues. Simultaneously. To both trios. How else to explain this exchange?

"Ah! You can read... I mean, you are reading. Sorry. It's nice to see people reading. Not a lot of people read these days. People prefer to... hear. But all this 'hearing' is just reading for lazy people. Kids today should be prepared to pick up a book, and not just go around the whole time with all these modern... ears. Sometimes I just wanna rip people's ears off and say 'Read a book, for God's sake!'... Well, actually I'd probably say 'Read a book' first and then rip their ears off, otherwise they wouldn't hear me, hehehe... Actually, I probably wouldn't rip their ears off at all, I'm not a violent person. I like ears! Especially women ears, they're my favorite. I don't mean I collect them or anything! I don't have a big bucket of women ears hidden away somewhere. No, No, No, I'm not after your ears really. Not that there's anything wrong with your ears! You know if I was some kind of mad ear person, your ears would be the pride of my... ear bucket."
 * There's an episode of Red Dwarf where they all don sparkly jackets and sing Tongue Tied, a song about this experience/
 * Xander from Buffy the Vampire Slayer does this when he meets the eponymous character. He wittily remarks, "Maybe we could...hang out at school, since we both...go there." He lampshades it immediately afterwards: "'We both go to school.' Smooth."
 * Jeff from Coupling talks a lot of gibberish normally, but it gets oh-so much worse when an attractive woman is involved. In fact the trope Digging Yourself Deeper used to be called "Bucket of Ears" after the following attempt at picking up an attractive girl at the bar:

"Goodbye... Hang on, sorry, said that wrong. I didn't mean to say "goodbye" like that... I mean, don't be alarmed. It's not because I think you're about to die or anything... No, truly. I think you've got years yet! I mean, you look really healthy - and I'm sure you have regular check-ups in case you've got one of those terminal illnesses with no visible symptoms! Though who can tell these days, right? I saw a friend of mine once, looked the picture of health. A week later I went to see him being cremated - not that I'm going to go and see you being cremated, of course - Though, I mean, I would go to your funeral if you suddenly died for any reason. I'd love to... So, how are you...?"
 * Steven Moffat, writer of Coupling, also practiced this technique in his previous show Press Gang, with character Colin Mathews:

"Ross: Hey, uh, you know that smell gas has? They put that in. The gas is odorless, but they add the smell so you know when there's a leak. A lot of other gas smells. Methane smells... [Afterwards, Rachel apolagises to the Pizza girl] Rachel: I am so sorry for Ross' flirting. Pizza Girl: [stunned] Oh my God! That was flirting?!"
 * Ross in the Friends episode called, appropriately enough, "The One Where Ross Can't Flirt" has trouble flirting with the cute pizza girl:

"Bernard: Do you eat? I do. Do you want to do it in the same room, sometime? Kate: Umm well... Bernard: You're busy! You're probably seeing one of your four million friends. Never mind."
 * When Michael Bluth met Rita for the first time, he very unreassuringly reassured her that his interest in her was not to stalk and kill her like Jack the Ripper. Fortunately, (or perhaps not,).
 * George Michael was never that bad with Maeby, but he seemed to lose control of his stream of thought whenever they talked.
 * In Black Books Bernard attempts to ask a women out with the words below. It actually works, in that she, after confirming that he was trying to ask her out, accepts.


 * This happened to Sherlock when Irene said brainy being the new sexy. John's face after Sherlock's verbal keyboardmash is priceless.

Music

 * The Police song, "De Do Do Do, De Da Da Da."
 * Also implied in "Every Little Thing She Does Is Magic."
 * Two Steve Miller songs ("The Joker" and "Enter Maurice") had the phrase "Pompatus of love". 'Pompatus' is a made-up word. (Fun fact: A film called 'Pompatus of Love' was also made, discussing the meaning of this made-up phrase.)

 * Fate Stay Night has our hero Shirou working with this in just about every route once the girl chisels through his sheer thickness.

 * If you opt to romance Tali in Mass Effect 2, she spends the first couple of conversations stammering like a kid.

Web Comics

 * Eight Bit Theater: Black Mage sees White Mage for the first time, and the first things out of his mouth are "Hubba flubba wabba zabba." He collects his thoughts to attempt to woo her, but fails again. "I am the Black Mage! I casts the spells that makes the peoples fall down!"
 * Dumbing of Age: When Walky first meets Dorothy, His intelligence drops from Smart Ass to Buffon, culminating in throwing a toy at her screaming I GIVE IT TO YOU!"

""I had to chat up girls, and I'd only tagged them before. I didn't have the verbal power to be able to say, "Susan, I saw you in the classroom today. As the sun came from behind the clouds, a burst of brilliant light caught your hair, it was haloed in front of me. You turned, your eyes flashed fire into my soul, I immediately read the words of Dostoevsky and Karl Marx, and in the words of Albert Schweitzer, 'I fancy you.' " But no! At 13, you're just going, " 'Ello, Sue. I saw you in the room... I've got legs, have you? Oh yeah... Do you like bread? I've got a French loaf. [mimes smacking her with the loaf and dashing off] Bye! (I love you!)""
