My freshman year of college, which wasn't too long ago, I was flipping through channels getting ready to go to bed when I heard a ruckus. I went ouside and there was this kid trying to start a fight with some other guy. He was obviously drunk, I figured.
So, I told him to be cool and calm down and leave. He finally decided to and on his way out bumped in to a girl. He then grabbed her by the face and shoved her against the wall. I kicked off my Dale Jr. slippers and proceeded in backing him toward the door cursing, etc.
About a eye blink later I was seeing spots. I snapped out of it and noticed he was choking me out. I punched him in the face about a dozen times...nothing. I slammed his head against the wall...nothing. Finally I just got him down and beat the dog shit out of him until he wanted to quit fighting...he never did. I ended up having to hold him to the ground in an armbar for about 15 mins before THREE big cops cuffed, shackled, and zip tied his ass. I later found out he had drank a fifth of Jack and had done enough PCP to literally disable a horse.
Now every time I am around one of the witnesses I get the "Hey, tell that one story about kicking that guys ass in your house slippers..." bit. Anyone else would have done the same thing, but I never expected it to happen to me.
ETA, I feel your pain, I worked as a bitch-boy at a grocery store during high school. I was pretty sure I was going to get my ass kicked by big brothas because they wouldn't let the buy a pack of Liggett Light 100s with our tax dollars.
