You violent so and so's you.
'course, you shouldn't really be ****ting anyone in the head with a closed fist. Remember that the skull is the thickest bone in the body (there to protect the nerve centre- for those of us that have them! lol)- even with a glove on, you're far more likely to break your hand (aparently even boxers don't go full pelt to the head). In fact, you'll hurt your hand more without a glove on.
Moral of the story- if you're gonna smack someone in the bonce, use an open hand. And getting a hard dry slap and going down has gotta put a seriously great dent in anyone's pride!!
