buttstain-brown 

The color left in underwear, bed-linen or elsewhere, usually in a streak.

Do you want your peanut butter spread thick, or just buttstain-brown?

I like the color of that table, not as dark as walnut, not as light as maple, more of a buttstain-brown.

buttstinker 

Butt stinker: A person who's rear end stinks. Typically the smell from a Butt Stinkers backside will show itself as soon as you are within arms reach of the person. Example: I went to talk to Billy, but as soon as I got close all I could smell was the stench from his ass, He is a butt stinker. Breaking the seal : this refers to when a butt stinker uses the bathroom prior to you. Upon entering the room ,all you smell is butt, yet all the person did is pee. Hence they broke the seal.
