I am sure everyone has a few of these stories.............someone get's drunk and passes out and then gets owned. I have 2 such stories.
When I was in college the West Coast hot spot for spring break was Palm Springs. Literally thousands of college students would take over the town. The main drag, Palm Canyon Drive, would be a 3 mile long traffic jam of people cruising in their cars and guys riding pocket rockets with girls in thongs on the back. Our 2nd night there we met 4 girls and invited them back to our room to party. We were all getting drunk and smoking some great herb when Jason passed out cold on the bed. We decided he was fair game. The chicks pulled out their makeup and did his whole face up.........eyeliner, rouge, lipstick, etc.... They undid his pants and poured a full salt shaker down his crotch. For their finale they took a tube of toothpaste and speared it all over his lips. We figured that he would wake up in a rage so we all left. We came back about 4 am and he was still out cold. When he woke up in the morning, I guess from the toothpaste his lips were swollen to 3x their normal size.

He asked what happened and we told him that he started making out with one of the girls so we all bailed to leave them alone in the room and when we came back he was alone and in that condition. He believes that story to this day. We ran into the 4 girls again the next day and he scared them all off when he started screaming at the girl he had been hitting on.............."What the fuck did I ever do to you?" He was a bit difficult to understand, though with the biggest set of nigger lips you have ever seen.
That same year, about 15 of us were having a little party in my roommate's girlfriends room. Suddenly there is some kid in the room that none of us know. He tells us he is a high school student who had applied for admission and was at the school for an overnight visit. He was assigned an admissions host who was supposed to take him to their classes, show him around the school, etc... The ad host evidently ditched the kid. We let him stay and gave him a few drinks. He was a real light weight and about 30 minutes later puked on one of the beds. A few guys picked him up and carried him to the dorm lobby and put him onto a couch. Evidently about 3 am, some people came into the lobby and saw him passed out on the couch. It was the last week of the school year and there were giant dumpsters behind every dorm to accomadate all the crap everyone threw away as they moved out for the summer. These guys picked up the couch with the kid on it and carried it outside and put him and the couch in the dumpster. It was one of those dumbsters that looks like a truck trailer with big doors that swing open in the front. He slept until the morning and was discovered by campus security screaming for help because he couldnt figure out how to get out of the dumpster.
I'm sure others have far better stories, but those are mine.
