Irwin! ( poker )



Presto (In Hold'em, what one says when revealing pocket 5's.
This term is still evolving and subject to redefinition.
The term comes from a more well-established background in Blackjack where one says
"Presto!" when turning over a blackjack. When a player says "Presto!" at an appropriate time,
the correct countersign is to say "Irwin". This is a method of identification, not a compulsory ritual).
