My neighbor is such a frickn NAB! She peeks through the cracks of our fence to see what we are doing. You can't even come home from the store without that NAB spying on us! One of these days I'm gonna freak that NAB out! When we need to give eachother a heads up because she's outside we say, oh NAB so she doesn't know we are on to her.

Function (n.) - Abbreviation meaning "Negligible at Best" (the misuse of the word negligible to mean negligent in this context is deliberate). To be used when someone is being an unfavourable character, doing something unfavourable, or when someTHING is unfavourable.

A talented girl who has many friends both girls and guys. She is called a "whore" most of the time for wrong choices. She likes to experiment with new ideas of love and loves to be wild and party. She is not afraid to make the first move, but then again she is not scared to punch everything out of you.
Oh that Nab, she made out with ANOTHER guy?
