A Dirtball Durbin is usually a dirty-brown haired male, who is almost 100% of the time gay. He is always looking to get butt fucked, and doesn't ever get any pussy. Dirtball Durbin is the dirtiest of the dirts, and is known by everyone as a Dirtball. The only time a girl calls him cute is out of pity.
Person 1: Look at that greasy faggot over there!
Person 2: Hey, that's Dirtball Durbin!
