When your walking down the street, maybe with a friend. And you see a bum just sitting, standing, or laying down. You step back, take a deep breath, and sprint toward the bum at full speed. once close, you crossbody him in mid-air, once on the ground you beat the living fuck out of the bum. BUMRUSH.
