Halisen

A folding fan made of heavy paper, used primarily in Japanese schools for the purpose of class representatives and teachers to smack unruly or stupid people upside the cabeza

Student #1: *looking at ecchi mags under his desk*

Class Rep: *catches him in the act and thwaps him several times with the halisen while screaming "BAKA HENTAI!!!"
