a movement created by mostly urban african americans to intimidate witnesses and stop informants from getting them in trouble. a large red stop sign with "snitchin'" directly below it, supports this movement. sometimes associated with drug trade/dealing and/or violence (usually gang-related) in urban areas.
"did you see that shirt ______ was wearing?"
"no, what did it say?"
"it was like one of those street signs that say "no parking anytime" but it was modified to say "no snitchin' anytims <---->""
"hahah, he should stop snitching"
A campaign that pushes the idea that any african-american who reports any crime whatsoever to the police is a traitor. Quite popular in the gangster rap scene. This has been very effective in reinforcing the racist stereotype that all black people are criminals.
Maybe instead of "Stop snitching", the motto should be "Stop committing crimes".
