Especially if you are sweating like a whore in church and screwing your face up as if you are constipated.

V. To Classturbate,
masturbating during class; most often by a guy, often creepy, with few exceptions.
The subject will most likely not know everyone does, though.
Guy: Dude! You hear about Vincent Frank?
Girl: No, what about him?
Guy: In two days so far, he's classturbated in 7 classes!!
Girl: That's just creepy.

And the weird part, this is a true story.

And yes, a teacher will notice.
in this case, she has
