Button (poker)

The term button is also used for a variety of plastic discs, or lammers, used by casinos to mark the status of players.

According to Martin, the earliest use of the phrase in print is in the July 1865 edition of Weekly New Mexican: "They draw at the commissary, and at poker after they have passed the buck."

U.S. President Harry S. Truman was noted for a sign in his office reading "The buck stops here."

It was a gift from [citation needed] Fred Canfil, who found a similar sign in the warden's office at the Federal Reformatory at El Reno, Oklahoma.

While in most home games, the player holding the dealer button deals the cards, in a casino or cardroom, an employee handles this responsibility.

Which of the two differently marked lammers is used depends upon the requirement to trigger the kill pot for that game.
