The art of choffing is for a female to vigorously pound herself at a rate of pace not normally known to man. Usually when the choff is finished, the womans hand is completely coated in a mix of cum and blood. Tasty.

His version of the story was pure schmegegge.
The whole schmegegge was made up to get Liz a little bit of attention.
