When in the course of your day you took a big dump but was unable to get your ass crack as clean as it needed to be because of those lame ass little toilet paper squares in the high school bathroom or the local gas station.

Stink butt usually comes into play when it inhibits people from having sex until they have had a proper bath.

I wanted to make it with the chick but I knew I had a bad case of stink butt.

Hey, take a shower first... you have stink butt!
