In full court basketball, "cherry picking" is a derogatory term for when a player does not get back on defense, instead camping out at his team's offensive end and waiting to receive a long pass from a teammate to score an easy, undefended basket.
Cherry picking is not technically illegal under most forms of basketball rules, but it is widely frowned upon as unsportsmanlike and also lazy. Accordingly, "no cherry picking" is often considered an unwritten rule of the game that is enforced with bullying, mockery, and ostracization, as necessary.
