Hmmm… While I’ve only been in one real ‘fight’ (got sucker punched and fell down, but was fine), I do have several years of training in shotokan karate. Basic strikes, blocks, holds, etc etc. I also get quite crazy when I’m angry and the adrenaline is pumping, although I’ve never had a chance to use this in a fight. I spar regularly in karate and I can hold my own, but honestly that’s so different from a bar fight it’s not even funny.
So, in summary I would be ok, but nothing special. Maybe if I start training like pravnik… (seriously, I’m impressed!)
I’m pretty good at throwing people around and have enough high-school wrestling experience to know how to grapple. As for causing damage with my own fists, I’d be useless.
To borrow from So I Married an Axe Murderer, I practice the Gaelic martial art of FUKYU! It mostly involves headbutting and kicking them while they’re down.
I imagine I’d be okay. Not great, but not completely useless either. I’m a small young adult female, in decent shape. Girls, especially small girls, tend to be taught very young that the world is a very scary place, and people are out to get them. Corner one, and you have probably just cornered someone whose street-fighting style could be compared to that of a house cat on PCP. Small terrified girls eye-gouge, claw, bite, kick and stomp anything they can reach.
On the other hand, because I’m a small girl, I think I would have to try fairly hard to start a fight between me and some guy, even in the sorts of places where fighting is common. As was mentioned above, most guys of the habitual bar-fighting variety won’t hit girls, even if the girl in question is trying to maim and/or neuter him. If he fought me and hurt me, his friends would beat the snot out of him for hitting a woman, and if he fought me and lost, his friends would beat the snot out of him for losing to a girl.
A much more likely scenario is that someone would pick a fight with the guy(s) I was with, ‘on my behalf’, as it were. In that case, if someone were getting really stomped, I would probably do the stupid thing and try to sucker punch someone, swing a stool, or otherwise distract the attackers as much as I could. When a 5’2" woman jumps on you from behind, loops a forearm around your neck, and yanks backwards while kicking one of your knees, it is surprisingly effective at landing you on the floor.
