Spunk trough 

A spunk trough is that hollow at the bottom of a womans back, right on her spine, that appears when she's on her hands an knees. It is most prevelant when she arches her back during doggy style. The goal is to fill it.

She was bent over the bed and I was getting her from behind. I pulled out just in time to finish on her back and nearly filled her spunk trough.

I sold you an ounce of skunk, and you thought it was a four and a half. 

Insult. Often described as the worst insult around, if someone uses it the reciever has been known to pass out with lyrical shock.
First heard used by the MC: Devilman against Skepta in lord of the mic 2.

person 1: your rhymes are swag. KMT
Person 2: o yeah?, well I sold you an ounce of skunk, and you thought it was a four and a half.

Person one passes out.
