Life is full of things that are unnecessary, needlessly unpleasant, and stinky. Butts are one of them. We all have at least one in our lives. Buttness can be used to describe anything that is awkward, uncomfortable, and makes you say "Was that really necessary???" It feels most at home in situations where you look back and realize that there really was no good reason for what you just experienced.
