Classterbating.

To jack off in class, if you go to a LAP TOP school, and you sit in the back, have a party!

When you shake your dick in class, to a porno on your laptop, its Classterbating.

classeration

Any cut resulting in severe bleeding, or necessitating the need for stitches, at any cultural event, including but not limited to the opera, an art gallery, or a Dixie Chicks concert.

The emergency response team arrived at the Sidney Opera House only to find that Sheila Koalawanker had suffered a life threatening classeration caused when during a particularly poignant performance of Fiddler on the Roof, the bow of the 1st violonist became a ballistic and travelled through Sheila's carotid artery.
