Or "backsauce"
A lazy version of the word "backsass", and a variation of the word "back talk".

Literally means, talking back or responding to someone (mainly an authoritative figure) in an opposing and sometimes smart aleck-y manner.

The sauce that comes from out of one's back. Typically from a pimple, cyst or magical portal, back sauce is potent, thick, creamy and extremely rare in small communities. It is more common in metropolitan areas. People with back sauce build-up are, on average, stupid and have hair on their heads. They are hard to spot. Beware of the "back saucers". They are aggressive and very agitated due to the back sauce build-up. Avoid eye contact and any form of communication with a back saucer.
