beat him up

It's about to go down. Nobody bites Steve in your presence and gets away with it. You try to remember the one fight you were in during recess in seventh grade. The sound of fists repeatedly hitting flesh resonated on the playground that day. Unfortunately you were the one being beaten up but you remember the stance and agility of that eight year-old bully like it was yesterday and know you can reenact it. Do you punch him or pull his hair?
