Bellisario's Maxim: The author's comment on N and Black's weapons: "Don't ask how their weapons work, they just do."
Fan Nickname: Thunderpus, Thun-duuurrr-us, Derpurus: Thundurus, for his immensely memetic facial expressions.
Also, Thundhurrus, if only for a resident Troll on the boards who goes by that name.
I Knew It!: Considering the rampant Wild Mass Guessing in the comment boards, fans have managed to predict a few things and get very vocal about it. Kcalb caused an uproar of "I CALLED IT!!" in episode 14.
Memetic Mutation: A lot of the series' awesome facial expressions have been appropriated as reaction images.
