Another name for sexual lubricant.

Can you please pass me the social butter so that I can engage in sexual intercourse with my significant other/random hook up?

fly in the buttermilk 

A single dark skinned person surrounded by a group of light skinned people. Possibly, but not necessarily a token black. A racial variation of fly in the ointment.

Jackson: This is my school picture from the early days of desegregation.
Williams: You look like a fly in the buttermilk.

Aaron did not realize that he had only been hired to make the company seem as if it promoted racial diversity. He became discouraged on the first day of work at the firm when he realized that he was the fly in the buttermilk.

nutt butter 

The hot creamy ejaculate from the male scrotum. Sometimes utilized as a tastey protein spread. Not to be confused with Nuttela.

Janet yearned for my nutt butter so I gladly obliged her by exploding a vast amount of nutt butter into her voraciously eager mouth.
