A Dirt Bird can also be someone who'll do anything to finish something, low morals. A person that'll stoop to anything, basically.

A variation on snowballing. it is after a woman performs oral sex on her guy... but without swallowing or spitting out the spunk. She then goes to his ass ... or another individuals ass and spits the spunk in their trunk.
when Bridget finished sucking my C**K she took my load and dropped it in my ass that was dirt balling.

Much like a hillbilly, but even lower on the scale, since here in Michigan, they don't even have the benefit of a hill's potential scenic value, since the land is so damn flat. These ass-backward bumblefucks are just out the middle of big flat nowhere with nothing but dirt. Characterized by decaying, halfway or completely caved-in barns, various cars or trucks on blocks with weeds growing up through them, "yards" cluttered and basically unmowable from so much junk, extreme ignorance, as well as paranoia in thinking that anybody is actually going to steal or vandalize their broken old crap.
After we went 4-wheeling down his fence-row (not even in the fields), to get to the riding trails, the dirtbilly neighbor came out with his shotgun and threatened to shoot us for "messin with his poperty".
