Some asshole flirts with Your girl

Big football jock hero Robbie Helms is swigging beer like he is a fashion model. He is talking to your girl with that cocky grin on his face. You watch with rising anger. He puts a meaty hand to her arm and you walk over. "Back off there boy", You tell him. He laughs and asks "Or what?". You rise up your left arm and Robbie gets ready to block, but you strike him with a surprise right that slams him to the ground hitting his head hard. Robbie is crying like a little bitch. He runs out of the place, you boot him on the ass on the way out, nearly knocking him over.
