1.
Aco
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".
