Jackie:I wouldn't use real money to play poker on a bet...

Aw, Jackie, it's not realif there is no chance you're gonna lose real money, be a penny or a pound.
"In for a penny, in for a pound" as they say.

Here in New England "Ante Up" is often used whenever a risk is involved. A sort of fast way to say "Put your money where your mouth is."
And - she said making a WAG - I'd guess that "post ante" could be used to apply to a post mortem on a game!
