To vomit from drinking too much. The mouth is like coins coming out, and like a one-armed bandit, the arm is up from holding one's hair out of the way, or from a toilet or
whatever you are handing onto. Most don't
even notice the
irony, of all what one wins when one is excessive and greedy.

got too
drunk last night, hit the jackpot, and got
puke all over my new trainers too"
