Your friend(s) show up at your apartment when you are trying to sleep looking for your roommate, and you tell them he isn't here, so they proceed to walk in anyways and make themselves at home, thus keeping you awake and preventing nappage..
I find it irritating when people make stupid threads........
j/k.....
I've never had any roomate's friends try that on me before. I've always been that guy who people aren't too sure about mentally. So people know not to test my boundaries....lol
