When you stop someone from having sexual relations with a member of the opposite sex. Commonly used so you dont have to call your girlfriends best friend a cock block in front of her.

Rooster= cock, Wall=block

see cock block
Man 1: I almost got in my girls pants but her friend kept calling so we had to leave to pick her up.
Man 2: Damn. Rooster Wall-ed
