Steamer poker
One who is on tilt (Playing poorly and irrationally due to
emotional upset, often caused by the player in question having
had a good hand beat by a freak draw from another player (often
in complete disregard of the odds and good play) or the player
having lost a pot because of his own bad play. Also called steaming,
having one's nose open, opened up, unglued and being wide open.).
