Nuh uh: A way of saying "I'm a gay furry femboy, 5'2, I sound extremely feminine."
Them: Yo, are you a furry?
Me: Nuh uh
nuh uh pass is a concept invented and controlled/owned by Elia Al-Nims where if anyone says "nuh uh" to you or "nyuh uh" or anything with a similar meaning, then it doesn't count and also whenever you say "nuh uh" or "nyuh uh" or anything with a similar meaning, then it automatically overrides and overpowers anyone else that says it. Only certain people have access to this pass.
