Presto (poker)
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.
