Dirtbagz are grott, they tend to approach you with foul manners using the occasional friendly gesture. they spend time rubbing poles and pointing out the most outrageous things. They are rude and obnoxious and generally are break dancing alcoholics.

The term comes from the ancient Greek meaning "You are so freaking filthy that my outhouse holds its breath when you get near it" Thanks to our loving and accepting modern day society, the word has now become an appropriate replacement for words such as sluts, people with unibrows, gays, steroid users like Barry Bonds, hicks, cheaters, and people that will do anything to put themselves ahead and feel no shame whatsoever.
"Wow that bitch has a thousand and three STDs. I'm pretty sure she's been a dirtbag the last couple of months."
