On (poker)
1) Up to; that is, referring to the person on whom the action
has stalled. "Who's it on?" means "Whose turn
is it?"
2) In agreement; usually about a bet, a proposition, or a drink
pot. "Are we on?" might mean, "In reference to
my suggestion that we both put all our chips in the pot and
take four cards, will you go along with me in this sporting
endeavor?"
