Baka and Test/YMMV

"Minami: Watashi...
 * Nightmare Fuel: In the Eva Parody episode,Yoshii's screams as his Avatar and he share the pain of attacks sound a little too close to Shinji Ikari getting fried up by Ramiel.
 * Black Comedy Rape: In episode 7 of the second season, Yoshi looks around for people who could help him. He sees Shouko trying to take off her yukata and get intimate with a gagged and tied Yuuji, clearly trying to scream. He concludes that Yuuji can't help him and turns back to his own situation.
 * Crazy Awesome
 * "Ironman". Some teachers have special characteristics, such as different summoning ranges, faster test-checking speeds, and lenient test-grading... but his is an extraordinary ability to move around such that he can appear everywhere: classrooms, ventilation ducts, public bathrooms... you name it! His skill is even mentioned in the show as he follows Kouta/Voyeur in his Dynamic Entry through a closed window to allow a key battle.
 * Ironman is the wild card in the show, as he can allow battles in any subject.
 * He's surprisingly empathetic, intuitively understanding why Mizuki needs to alter her 2nd placement test. He also correctly guesses that there's an important reason for Yuuji and Yoshii's hijinks. See CMoA below.
 * Crowning Music of Awesome
 * Baka Go Home.
 * Every time Miharu clinging to Minami, this classical high paced music is actually a good one.
 * Designated Villain -- Yoshii in episode 10 of the second season. While he may have somewhat deserved the harsh treatment he got, he isn't the only one at fault. He may treat Minami like one of the guys, but that's partly because she's always beating him up, at times with only the slightest provocation. Not to mention, Miharu is one of the last people to tell Yoshii that he doesn't treat Minami well. Especially since she gave the What the Hell, Hero? speech right in front of Minami, and reduced her to tears.
 * Ear Worm
 * The opening and ending themes of the anime.
 * That also work for the second season opening and ending
 * Ensemble Darkhorse -- Hideyoshi.
 * Fan-Preferred Couple: Among all of Aki's possible love interests, Hideyoshi Is the only one that has yet to physically assault him. And as of the later light novels, the feeling is apparently mutual.
 * Ho Yay
 * Just watch the ending.
 * Kicked into overdrive by Episode 3 with Akihisa and Toshimitsu. Episode 5 also has Toshimitsu unable to open Akihisa's locker out of fear someone would think he was putting a love letter in it.
 * Akihisa and Hideyoshi
 * In Episode 5, Akihisa called Hideyoshi cute, then invited him to the Kisaragi Theme Park using a couples-only ticket. Akihisa wails when Hideyoshi rejects him, complete with a "crashing waves against the cliffs" scene, but later confesses to him through Insane Troll Logic. It doesn't work. Later on he blushes when Hideyoshi falls victim to Stripperiffic Clothing Damage, complete with Bishie Sparkle.
 * In Episode 6 Akihisa imagined Hideyoshi in a swimsuit, once again surrounded by Bishie Sparkle. Followed by joining Kouta in the Corner of Woe when Hideyoshi decides to wear trunks, only to be subverted when Hideyoshi comes out wearing very girly trunks and a swimsuit. Cue both guys having nosebleeds until they've ran dry. They start nosebleeding again when Akihisa accidentally pulls Hideyoshi's top off.
 * Season 2 Episode 4: Mizuki gets an Imagine Spot with Akihisa and Hideyoshi. She doesn't take it very well.
 * Season 2 Episode 9: Hideyoshi shows Minami how acting's done by way of a very convincing faux-confession.
 * In Episode 8 a malfunction of the Being System leads to a quite... interesting scene between Yuuji and Kouta's Summoned Beings. It doesn't help that both have been turned into Bishonen.
 * And in Episode 9, we have the Yuuji-Akihisa combo from Episode 1... and it's back with twice the implications and triple the dose!
 * The Christmas Episode DVD extra has the characters being asked by the Narrator what Christmas means to them, before the cult members of class-F interrupt them to correct them. It starts with Himeji, then Minami, then Hideyoshi, then Akihisa/Yuuji/Kouta. All of them are played out in the exact same sequence, ending with a tall male character walking up to them, with the camera panning close to their feet while they lean up to him for a kiss. Yes, even for the guys.
 * The cult members all beg Hideyoshi to go out with them at the end of his segment.
 * As Of Volume 10 Akihisa has official kissed another guy on the lips, although to be fair he didn't mean to.
 * Moe Moe
 * Hideyoshi is the king/queen of trap moe.
 * Sweet and cuddly Himeji-chan.
 * If you want Yandere Moe Moe, you've got Shouko.
 * Hazuki Shimada is adorable, especially when she goes "Baka Onii-chan".
 * Even Yoshii in a Meido outfit, much to the amusement of Himeji and Minami.
 * Jerk Sue -- Shouko.
 * Memetic Mutation -- From Season 2, Episode 8:

Akihisa: What a shit?

Minami: WHAT A SHIT MAN YOU ARE!

Yuuji: She means you're such an idiot."


 * Memetic Sex God -- Hideyoshi.
 * The Scrappy
 * Minami. Season 2 only makes things worse. Then she is Rescued from the Scrappy Heap when she gets her backstory episode. It also helps that afterward, she and Yoshii had some moments that weren't filled with anger or violence.
 * Miharu Shimizu as well. Season 2 made things worse in her case as well. And she doesn't really get better, unlike Minami.
 * The Unfair Sex -- Can cross into this from time to time due to Double Standard Abuse (Female on Male)
 * Unfortunate Implications -- In Class F there are only 2 girls, one of which is only there because of illness, while the other is only there because of her difficulty reading the kanji. Can only guys be truly stupid?
 * The Woobie
 * Abusing Yoshii is funny and sad at the same. And then there was that one time he took that history exam and got a zero because he wrote Alexander the Great where his name was supposed to be.
 * Shouko gets a rare one in episode 7 of Season 1, when she runs off stage in a wedding dress after getting mocked by another couple that she's got a stupid dream of wanting to be Yuji's bride. Yuji decides to have a little "talk" with said couple later on, and presumably beats up the guy, as he looks like he's been in a fight after he catches up with her later on.
