Loser ( poker )



1) A losing player.

2) A player losing. (There is a distinction. Definition 2 may be just a temporary situation, while 1 implies permanency.)
"I'm loser today." (The implication here is that, yes, today I'm losing, but that will change.)

3) A losing session. "I booked a loser my last three plays."

4) A hand that cannot (or probably cannot) win in a particular situation.
"I can't call; I know this straight is a loser.
