In modern day United States, Roshambo or Rochambeau is when two or more guys kick, punch, squeeze, or knee each other in the groin to win something (an object, money, bets, etc..) untill one of them gives up or falls down. The last one standing wins. This is a modern American twist on the game.
It is also a very old word of Egyptian origin for the child game Paper, Sissors, Rock.
In the TV series South Park, Cartman and his friends play the game Ill Rochambeau you for it, by kicking the opponent in the crotch. The first one to fall over loses the game. This of course means the first person to go is usually the winner. This is a way of choosing, and its called Rochambeau.

After: Jean-Baptiste Donatien de Vimeur,
comte de Rochambeau (1725-1807).
As a lieutenant general, comte de Rochambeau commanded the French expeditionary army sent to help the American Revolution during 1780 to 1782. His skillful leadership and professional wisdom were vital to the American-French allied victory at Yorktown in September 1781.
Rochambeau was so skilled at kicking the Britishs balls in battle, that his victories were called Rochambeaus.
His name, in corrupted spelling, became slang for any number of contests or confrontation resolved by competitive nut-kicking.
