Basically, Nigger Slammed simply means, when one or more niggers carelessly backs-up their old piece-of-shit jalopy into a brand new, clean, nice 'White Man's' car. All because he or she is a stereotypical Nigger.
"Hey bro! What happened to the bumper of your new Challenger?!"

A faux relationship between two non-committed people based on having sex without looking "slutty" under the false pretense of actually being in a relationship together. Both parties are desperate in their failed attempts at love or getting laid and are usually too unattractive to be successful in this area. Both parties are pursuing other sexual relations. The couple is just "slamming" in the sack as they have settled and have had to resort to having sex with eachother.
"I'm glad even ugly can find love!"
"No, that's just slam crew. Don't be fooled. They are both sexing other people at the same time. It's gross and the charade is sad."
