The Natty to Slampiece Ration (NSR) is the mathematical law defining the fixed ratio of Nattys to Slampieces in a given area at any given time, per 1 Bro. When N= natty and S= slampiece, the ratio is as follows: S>N.
For instance, if there is 1 Natty, before the Natty can be consumed, there must be at least one slampiece in close proximity to that natty. This law is closely related to the Bro to Slampiece Ratio (BSR) and the Natty to Bro Ratio (NBR).
Bro 1: Bro, i've got a real problem. I was about to pound a six-pack of Natty here but then i realized- I only have 5 slampieces! My Natty to Slampiece Ratio is totally unchill, bro! Can you help a bro out, bro?
Bro 2: Absbrolutely, bro. I'll be right over. It just so happens I've got an extra slampiece right here.
More suggestive, and therefore far more amusing, variation of politically correct, gender-neutered pansexual labels such as S.O. to refer to a sexual partner or boy/girlfriend. See also slamp, piece.
Sorry I haven't come in to work for the past month, i've been busy shagging my new slampiece full-time and couldn't walk straight.
