If you ever watched anime called Minami-ke and Liked Chiaki's method of giving nicknames to her classmates, you can do so here too!
Give a nickname which you think is suitable for the person above you.
Chiaki: *stares at the classmate judging him*
Chiaki: Plain yoghurt!
Classmate: T_T ...
Whatever goes! Just don't be insulting please. It's all for fun :)
