Classterbation

When one gets the sudden urge to bust a nut midway through class. Normally applicable when there is a sexy female in the area.

Student 1: Hey man, did you see that new girl? she was wearing a skirt and i classterbated after i saw her!
Student 2: Dude.... gross.. Classterbation is disturbing.
