Clubs poker
1) One of the four suits in a deck of cards, whose symbol is
shaped like a shamrock.
Originally, clubs may have represented the warrior class, the
club being an early weapon.
In the traditional deck, clubs are black. In the four-color
deck, they are green.
2) A club flush, that is, five cards of the same suit, all clubs.
"I've got a straight; whadda you got?" "Clubs."
