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."

Dude, my friend was crying and that dirtbag, (insert name), decided to be an asshole and smack them in the back of the head.

A dirtbag is a person with no life, No employment, No wife, No intelligence usually rapists and pedophiles. Dirtbags usually live in the wilderness or under your car, They mainly come out at night to scream in your face and grab your skin, and make random noise. Dirtbags usually live off the abusement of others, and anything they find off eBay. Dirtbags can mate with hobos producing Faggots. Do not approach a dirtbag. To spot a dirtbag always look out for their promiscuous smile and bounce like walk, They usually sound like Donald Trump but with more down syndrome.
