A slang word used to refer to a friend who is a backstabber, not a good friend, or just a really sneaky, slimy type of friend or acquaintance. In other words, a fake friend. The word originated from the 1993 movie Menace 2 Society, in which the lead character has a fake friend named Chauncy who sets him up and snitches.

Not only a derogatory name for your friends (Closely Resembling "Bitch" or "Punk") It is also a state of being, a way of acting or carrying oneself that causes your friends to question if YOU ARE IN FACT STILL A TRUE MAN.
As a name: You are a fucking chauncy, just walk it off...

As a reference to behavior: Q: You wanna drink beer and light things on fire?
Chauncy Answer: No, I am (a) tired OR (b)gonna spend time with my girl....
Either if these answers and actions are red flag warnings that your friend may be falling into A STATE OF CHAUNCY.
