When someone intentionally hits or checks the crowd at a show. Can be used to rile up a crowd or can be used to intentionally hit a certain person you don't like and is often used to provoke fights.
If you don't like someone at a show, intentionally start crowd checking them and everyone around them. if they hit you back you have a reason to beat the fuck out of them.
