Random thought of the day: Wouldn't someone with half an ass put more effort than people with a full one? Like when trying to sit upright, for example.
d'you mean flat-assed people like me? I dunno, but having a butt that's as flat as a plank proves to be an advantage when you're 1 of the three other passenders in a motorcycle :3
haven't though far enough to consider the flatness and roundness of asses. I'd think that even someone with an unnaturally round one still wouldn't have as hard of a time as someone missing half their heinie.
I was thinking vertically, with one hump gone and a similarly sized crater in its place. Horizontal might enjoy the same benefits of a flat butt and respect goes out to those who can work with a diagonal one.
