To refer to someone as the lowest of the low. The scrapings at the bottom of the barrel. A boiled sweet down the back of life's sofa. I pimple on the face of humanity. Someone who would scam you to the extreme and be proud of it.
when in a conversation with someone who has the morals of a dead cat, you can end your conversation by saying "Your so Aco".

aurora Colorado. here, you can’t tell if the banging outside of your house is fireworks or gunshots. belts are a no go and pants that are three to sizes to big are the shit. cars get broken into regularly and floors collapse underneath you at parties. the edgar haircut is overpopulated and all the white kids use slurs. to all the daddy’s money south shore and cherry hills kids, if you’re from Aco, you’re from the ghetto.
yo you here about that party getting shot up in aco last night?
