Having any one of these characteristics qualifies you as a fagroo, according to the DSM-IV:
1) you listen to gay music, such as "tokyo ghetto pussy" or "mc chris"
2) you are sarcastic and inconsiderate to your roommate's friends
3) you watch porn whenever you feel like it, no matter if people are around, not for sexual reasons, you just enjoy watching porn
4) you have an injury which is euphemized by giving it a human name, such as "dennis" or "little jeremy phillips"
Note: the origin of the word is the shortening of "faggot roommate." It is uncertain, but this may be Greek.
My fagroo was listening to techno really loud, and it scared my friends away. They think I'm gay now.
