Flapping the Floppy Cow

To masturbate in class, often causing you to breathe heavily and make your desk quickly move up and down. Derived from the infamous Van Fap Floppy Cow, the king of in-school fap.

Person: Van Fap, what the hell are you doing?
Van Fap Floppy Cow: I'm Flapping the Floppy Cow, why would I be doing anything else?
