Monro is a style of 8 ball pool gameplay strategy. The Monro philosophy is not one of winning but instead at any availableopportunity, even if detrimental to yourself, completely tuck up your opponent by snookering them.

Alex - *Decides to ignore the easy shot and snooker Steve instead*
Steve - … Did you have to play a Monro shot like that?!
