Non-exclusive Boys Club 

A group of racist bigots, both male and female, who believe they are cultured because they understand the basics of Cricket. Often found having ridiculous eating contests and using racial slurs, and, on occasion, both at the same time. They also tend to enjoy a midmorning bruncheon under a tree where a lynching has just occured.

"Dude, you going to the Non-exclusive Boys Club meeting today?"

"No thanks dude, I try to avoid all Confederate nostalgia that I possibly can."

exclusive non-serious 

Also known as ENS, this relationship status is increasing in popularity. Two individuals are involved with each other, and are not dating anyone else, however there is no commitment. It is understood that every waking moment of the day does not need to be spent together, as well each party does not need to inform the other where they are or will be at any given time. The words "girlfriend" and "boyfriend" are avoided and can be uncomfortable if brought up by a separate party.

Hey man, how long has Donnie been going out with Laura?

Well I don't know if they're "going out" as such, but they've been doing the exclusive non-serious thing for a couple months now.
