Beelzebub/YMMV

• And the Fandom Rejoiced: When it was finally announced there would be an anime.
  • That is getting better and better with each episode.
• Brain Bleach: Arandron in a bikini. Or a girl's school uniform.
• Complete Monster: The St. Ishiyama students that attack Shiroyama with a weight to the head. Normally that've would've led to permanent expulsion, yet alone imprisonment for homicide, if the cast wasn't Made of Iron.
• Crazy Awesome: Oga, the guy who convinces Arandron to teleport a polar bear into his room just so he can fight it.
• Ensemble Darkhorse: Because of the quirkiness of the cast, there are a lot of fan favorites, like Good Night Shirokawa, the Red Tails (especially Yuka), Azusa and Kazuya, the Shadow Group, Zenjuro, Isafuyu, Yolda, Lamia etc.
• Ear Worm:
  • Say it with us now: DA DA DA DA DA!
  • The fourth ED. Full stop.
• Fan Nickname:
  • Because of Forkas Rachmaninorr's name, people just call him "Doctor Awesome".
  • There's also the nickname Oga gives the Teimou students, the Krillin Bros, which has spread like wildfire in the fandom.
• High Octane Nightmare Fuel: This shot of Oga is drawn with such detail it has to fit the description of this trope.
• Hilarious in Hindsight: Aoi notes at one point that if Oga's rampages continue that the school would be destroyed.
• Memetic Badass: To some parts of the Fandom, 'General' Furuichi is this.
• Memetic Mutation: Hilda's status as the "Breast Idol".
• The Scrappy: Miki. Fandom reaction to him is about the same as Beel's.
• Tastes Like Diabetes: Chapter 139 deliberately does this for laughs.
