Muffin it

Named after a man called Muffin that quickly and somehow sneakily finishes a drink in front of his friends and/or assorted other bar goers. Different from chugging.

Dude, where did his drink go.
I don't know but I think I just saw him muffin it.

Muffintopulating

When a person, usually a female, wears pants that are too tight for their belly causing their fat to flow over the top of the waist of their pants.
