A sheetload is what you refer to when you've had a bowel movement in
bed, probably while you're asleep. Eventually you wake up and soon realize something’
s wrong considering the mess and smell. If you aren't sleeping
alone, your bedmate
will abruptly bring it to your attention. There is no denying what happened. If you don't have a mattress pad, you now have a nasty stain on the mattress. If you sleep bare-assed, the mess is even worse. Sometimes occurs when you're in
bed and go to cut a fart that turns out to be a wet one.
