A gay man that does not obsess about grooming, brand names and gay culture. Clothes are typically purchased at thrift stores so there is a slight smell of "dirt" or must about them.
He could care less about your new Prada sweater because he is a Dirt Fag.

A gay dude who can survive even the most chillating situations. Known for thrifting powers, and drunk showmanship, and knowing every other urchin on the southside.
"I went to the bar and ran into this totally awesome dirtfag who taught me about q-tips and making out while baking apple pies. I paid for his drinks, he congratulated me for supporting local homo."
