The act of going on a pub crawl with your (male) friends, and actively bumping into women's breasts without getting caught. Each time a player succesfully touches a breast they get one run, if they manage to touch both of them they get a four, and if they successfully manage to bag the nicest pair in the pub, they get a six. Players are out if they are slapped or otherwise rumbled, and can no longer "bat".
"Damn! Wilson's picked up 19 not out!"
"Shit, I went out for a duck."
