a shit in a toilet bowl that wraps around the perimeter of the toilet, yet still leaving a gaping hole in the middle

A bowlwinder is a mega-turd so great in length, that it actually winds around the toilet bowl like a soft serve cone at the Dairy Queen.
Dude, I think I'm going to be sick. I just went to take a leak in the gas station bathroom and somebody left a bowlwinder in there! I think it was staring at me.
