In a fight? Here is what you do, my friend.

Bring your chin down to protect your neck while continuing to stare in his eyes. Bring up your hands and say "I don't want no trouble ya hear". Flex your traps and core. Slightly bend your knees.

Here comes the important part. In a low voice begin to say "wolowolowolowolowolo" slowly increasing in volume. He should be surprised by now. Begin to sway side to side and loosen all facial muscles and your anal sphincter and your kegal muscle. By now you should be pretty loud and your opponent will have stepped back and appear visibly shaken.

Begin to piss and ♥♥♥♥ yourself and let your eyes roll to the back of your head. By now, you're chanting "WOLOWOLOWOLOWOLO" at the top of your lungs.

That's what you do in a fight, my friend.
