When I was going to K-State there was a rumor that some guy who lived in the dorm went to the doctor because he was waking up in the mornings with some butt hurt. The doctor examined him and told him that anal sex may cause some butt pain. The dude was like, "I'm not gay". Went back to his dorm room and found a bottle of ether in his roommates stuff. Replaced the ether with water. The next night after he went to bed, the roommate got out the ether bottle and put some on a towel. But when he went to put it on the dude's face he jumped out and beat him with a bat.
Never saw it in the paper so it was probably just an urban legend that guys in fraternities say to make living in a dorm seem gay.
