The act of masturbating during class. Or a derogatory term given to someone who does this act in class. This term can also be class jack or class whack.
I heard Nathan is a class fap in Mr. Harrington's Geometry class, those numbers must have really gotten him off!

I did a class whack to Beth this morning in history.
