First time I got rocked was last year at a party. Everyone was smoking and drinking and chilling, and my buddy has heard I'm pretty slick at BJJ and fancies himself to be good too and challenges me. Being drunk and high, I accept. We decide to do 5 minute rounds, first round is mostly him overpowering me and tossing me around, and me throwing submission attempts. I fucked his arm up with a nasty kimura but he got out and survived the round. Second round starts, I fake shoot, and as he's coming down to sprawl for it I catch an underhook and use a modified judo throw, mount him, drop into an armbar for the win. He's not content with this, so he says "Alright, how about you go against him, winner gets a dimebag." Points at a big dude, I go for it. Round sharts, he shoots, I sprawl, spin around and take his back and rear naked choke him out in like 8 seconds. Friend who lost before is still pissed and gets the biggest guy at the party to go against me for another dime. Now, my first opponent was about 220 lbs, the second was about 190, and the third was about 280. I'm 155 pounds.
So here goes the third match of the night, big guy takes me down immediately and starts working, and I end up throwing an armbar from the bottom and he picks me up and slams me on my head and everything went black and white and blurry, but I didn't let go of the armbar, and he tapped. About 20 minutes later it felt like I had taken a baseball bat to the dome.
Anyways the moral of the story, is don't underestimate the smallest guy at the party, because that person is usually me and I've never had formal BJJ training aside from submissions101.com, and I've tapped a purple belt and a brown belt.

I can't wait til Dollar General gives me my raise and I can start up at the BJJ place near me, lol.
