That's called a fat ____.
Seriously, when I taught, as part of an evaluation, a colleague shot a video of me for about an hour, so I could watch myself teach. It was then that I realised how much I was attached to my bar (teaching) stool. I sat on it in the front of the room, at the back of the room, and practically hauled it around all through the classroom. Everywhere I moved, it followed, like it was an object stuck to me rear.
That's one thing I'm aware of. I shudder to think what others there are. I think it might be a little odd to be carrying one of those folding seat, small as they are, around the temple. But being the only white guy, I guess the other regulars might think it's normal where I come from.
