look up any word, like spook:
The act of leaving work ten to twenty minutes before anyone else via a preordained excuse, and trying to be stealthy about it so that nobody catches wind of you exiting the door.

Also known as a "Parrish Pass"

While playing Texas Hold'em, it is the act of folding before the flop for a small bet ($1-$2) then getting a winning hand on the flop. Usually it is a full house or better.
I can't believe he folded a Jack/Seven suited when 3 sevens came out on the flop. That was a real jake out...
