There is nothing you can do to defend yourself that doesn’t take practice. More than a bit, too.
A generic defense? Sure, but again, without practice you will probably not be able to bring it off.
[ul][li]Recognize that you are going to get hit.[/li][li]It will hurt.[/li][li]It will not disable you.[/ul]In a street fight, mental attitude is 50% of victory. [/li][ul][li]When you become aware that you are about to be attacked - not after - you go into a crouch. Your hands are open and high, left arm aimed at his face, right arm inside his left arm.[/li][li]Come forward, blocking both arms whether or not either is punching at you. Either push his right arm down and across you with your left, or up and out, also with your left. Same with his left and your right. The idea is to give his arms something to do besides hit you.[/li][li]Throw a series of open hand palm strikes to his face. Right-left-right-left, coming forward and into him to put your weight behind the strikes. Aim at his nose, but eye or cheekbone or jaw is fine. These are not slaps - you are trying to drive your hand about two inches into his face, with a snapping return to give power to the follow up with the other hand. [/li][li]Hook both hands benind his neck and pull downward, hard.[/li][li]He will often react either by crouching, or stepping back.[list][]If he crouches, bring your knee up into his face.[]If he steps back, head butt him in the face.[/ul][*]Either way, shove him hard to one side, and run like hell.[/list][/li]
Take a self defense class if you want to learn something that actually might work. Notice that I said “self defense” - not aikido or tae kwon do or judo - self defense. Most martial arts classes do not teach self-defense - they teach duelling, where you are always fighting one-on-one in a well lighted gym with a smooth floor, where you know ahead of time what’s going to happen and have time to prepare. Real fights aren’t like that.
It is possible to find an instructor with an old-school approach to martial arts training that will actually prepare you, but this is very rare in the strip mall dojang environment of today, where H2H combat training takes second place to automatic belt promotions every three months (at $100 a pop). There are some arts out there - krav maga, non-Brazilian jujitsu, combato, some other of the modern cognates - that have not made the transition from fighting to fun and fitness with a dollop of Eastern mysticism, but these are few and far between and 80-90% of what you will be told is hype and sales pitch.
My $.02 worth.
