Another name for that wonderfully wacky game rock, paper, scissors. There are groups dedicated to the worship and analysis of this game. There is even a news group alt.religion.roshambo. There is a Worship of Roshambo web page. There is a e-mail based version Roshambo Rampage at Brunching Shuttlecocks. There are roshambo tournaments.

Search the web you can find lots of info about it.
