chug
vt. To masturbate. As a noun, you are a "chugger", and if you are a prolific wanker, you are a "chuggernaut". Derived from the imagined effort and sound effects that go into a wank, which is, honestly, the equivalent of the engine on an ant boat.
I recently noticed that Oasis fruit juice bottles have 'Chug It' written on the top, followed by 'open by hand'. Beat that.
