I got in a brawl with a tweaker once. Yeah, I had to choke him out, before he'd stop fighting. I hate tweakers. Who the hell carries a metal ashtray under their vest? I tackled him because I thought it was a knife. Half my size, and I ended up rolling on the cement with him. Was spouting all sorts of weird crap about being a member of the mexican mafia before I dove on him. I ended up on top of him, and he still didn't stop fighting until I started head-butting him.
Worst part was, when it was over, looking up at my friends just standing around staring at me. I mean, come on.
So yeah, tweakers suck.
Oh, and watch out. They always have weird weapons. They've sold off any firearms they have for drugs. Instead they have make-shift crap, straight out of a mad max movie.
