Air (poker)
1) In a lowball game, letting another player know whether you
are going to draw cards or not, sometimes letting the player
know how many, usually with the intention of getting that player
into the pot. Usually part of the phrase give air. "Gimme
some air. I'll draw two if you're drawing one."
2) Inadvertently exposing cards; usually part of the phrase
put air into [a hand].
"You'll like sitting next to Johnny; he puts a lot of air
into his hand."
That is, if you sit next to Johnny, the way he holds his cards
you can often see some of them, which, presumably, gives you
an edge (albeit an unethical one) on him.
