Rumors of Dustin's homosexuality erupted when he admitted to supporting Tottenham Hotspur. This was reiterated when Arthur, a known homosexual, also "came out" as a fan of Spurs.
It is a well excepted fact that Dustin has a generically masculine alter-ego known as Colt (or Coltstin). This is likely an unconcious attempt to compensate for his Spurs fandom.
Cowardice[]
Dustin is a well known coward. He enjoys to partake in delights such as taunting drunks from apartment rooftops, and then calling the cops in distress when the drunks try to kick the shit out of him and his friends.
