Victory Roll poker
In a draw game, at the showdown, spreading your hand triumphantly.
(It's usually done in the same manner that a blackjack or poker
dealer spreads an entire deck fanned face up on the table in
front of her. Spreading one's hand in this fashion, by the way,
is something of a needle, and is not practiced by a refined
player, who, when he has an obvious powerhouse, gently and diffidently
turns it face up on the table.)
