The Grim Adventures of Billy & Mandy/YMMV

Base Breaker- Fred Fredburger became this after being extremely overused.
- As was Mandy, after she became a Jerk Sue in later seasons.
- Billy, between fans who find him hilarious and fans who find him annoying and one-note.
Crack Pairing: Dean Toadblatt and a giant squid, canonly.
Crosses the Line Twice: The Christmas special. Features such things as a mall being burned to the ground as the Mall Santa is mercilessly beaten, evil vampire Santa, Santa's evil vampire wife, and the school bully being eaten by a pack of flying vampire elves. Really standard by this show's standards and not much until you consider that the average Christmas Special consists of a Crowning Moment of Heartwarming and are overall very sweet. Combine that with the fact that this is a children's show and you get a truly dark (and hilarious) episode.
Ear Worm: BRAINS, BRAINS, I WON'T LIE. I'LL EAT THEIR BRAINS UNTIL THEY ZOMBIFY!
Ensemble Darkhorse - Fred Fredburger, yes!
- He was this. Now he's the Base Breaker.
  - Now that the show's been long over, he's since returned to Darkhorse status.
- Jack O'Lantern has also gained himself a sizeable fanbase, despite only having appeared in a Halloween Special.
  - This is possibly the reason he was included in the video game.
- Dracula.
- Skarr, the only mainstay from "Evil Con Carne".
- Admiral Wolverine Lightningbolt.
- Sir Raven.
- The evil brain-eating meteor.
Family-Unfriendly Aesop/Spoof Aesop - Billy learns from his inner frat boy that, just because someone is different from you, you shouldn't be afraid of them. You should be angry at them!
Hilarious in Hindsight: In one episode, Grim is seen watching a My Little Pony parody called "My Troubled Pony" and enjoying it very much. Fast forward to 2010...
Jerk Sue: Mandy, Depending on the Writer.
Memetic Mutation - See Overly Long Gag,on the main page.
- Judge? Where are the nachos?
  - Yes!
  - I can spell my name real good! F-R-E-D! F-R-E-D! B-U-R... G! E-R! Fred Fredburger, yes!
- YOU DON'T TELL DRACULA WHAT TO DO! DRACULA WAS BORN KNOWIN' WHAT TO DO!
  - Vampires don't suck! They scrape! And lick! Scrape! And lick!
- Do not cry for him. DO NOT CRY!
  - YOU FOOLS! YOU'VE MESSED WITH THE NATURAL ORDERRRRRRRRRR!
  - IMPORTANT! COMMERCIAL! MESSAAAAAAAGE!
Moral Event Horizon - Grim and Mandy have done it too many times to count. Billy, though a good kid, has tried to kill his own "son" just because he's afraid of spiders. Irwin has allowed a Pyramid to be built in his honor, regardless of whether or not everybody remains brainwashed. Nergal turns people into his "Friends", civilians, unwillingly in his second appearance, including the viewer. Yeah, a lot of characters have crossed the Moral Event Horizon. The only reason the characters still put up with each other is because of Negative Continuity.
Most Annoying Sound: DESTROY US ALLLLLLL!!! DESTROY US ALLLLLL!!!
- To a lesser extent, any time Billy laughs.
The Scrappy: Billy is this to more than a few viewers, due to how arguably flat he is as a character.
- He's even this in universe.
  - Fred Fredburger is also this in universe, even managing to annoy Billy with his stupidity. Among viewers, though, he's a Base Breaker, with many who love him and many who feel he ended up over-used. (Although he wasn't half as over-used as characters like Cheese and Goo.)
- Mindy is one of the most annoying Alpha Bitches ever created.
The Problem with Licensed Games: Averted. The video game based on the series is a surprisingly fun beat-em-up style fighter with plenty of characters from the show, all voiced by their actual voice actors, with Weird Al as the announcer!
Toy Ship: Admit it- you've all considered this for Billy and Mandy at least once.
- Or Irwin and Mandy.
The Woobie - Grim. Sometimes a Jerkass Woobie.
- Pud'n.
- Jeff.
- Skarr. He is just trying to move into the neighborhood, trying to avoid his previous life as The Dragon/The Starscream under Hector Con Carne... He fails.
Tear Jerker: In "Son of Nergal", Junior attempts to fix his teddy bear, Mr. Bonkers, after Mandy rips its head off.

Junior: It's *sniff* going to be okay. I'll put you back together and *sniff* you'll be my friend and I'll be your best friend...

- Billy saying goodbye to his pet chupacabra Daisy.
Unfortunate Implications: Billy, according to the Christmas Episode, is Jewish. He's the character with the large, bulbous nose.
- This may be why it's never brought up again.
What Do You Mean It's for Kids?: There's Dead Baby Comedy all over the place. Seriously, the Grim Reaper is a main character and there's sex humor all over the place, and it's generally on par (and sometimes moreso what with Cartoon Network being much more lenient than Nickelodeon) with Invader Zim.
