I walked into my high school physics class one day and there was a chair suspended from the ceiling.  The teacher needed a volunteer, and I needed the attention, so I sat in it demonstrating whatever the lesson was.  When I slid off of it, my skirt came up and my underwear could be seen through my sheer black stockings.  The chubby Asian kid in the front row said, "Ewwww!" and blocked his eyes.  Seriously.  He seriously did that.
At least not all chubby boys found teenage Kat repulsive.
