Here's the thing with fighting. It's like, whoever wants to win the most, usually wins.
While it does matter how big/small you are, I have seen so many unusual fights, it's ridiculous how random it can seem. Even people who do know how to fight get fucked up by someone who hasn't thrown a punch in their life.
There was this big ass black dude on my street who reminded me of the one big guy from Friday. I was standing out in my front lawn watching this small tweaked out Asian guy pick at the sidewalk for dropped crack rocks (the dealers would deal en mass in front of my house). I see the big dude coming down the street and he yells something at the Asian guy. The tweaked out guy sees the black dude coming towards him and he looks like he's about to run, but instead he just lunges for the black guy's throat and instantly the black guy falls backwards grabbing his throat.
These two other guys start screaming and running up the street, so he just bolts out of there.
Dude had to go to the fucking hospital. He wouldn't get up and he sounded like his breathing was labored. An ambulance picked his ass up and I didn't see the guy for quite awhile.
My guess is that the asian guy put all of his force into a punch right in the adam's apple and broke the front of his neck.
The guy was down with just once punch.
