shit-up

Working out vigorously with full bowels, then trying too hard to get that 'last' sit-up. At least your whole anus didn't pop out, like has happened to some unfortunate weight lifters.

Weight lifter: *pant* *pant* uuHHUNNGHHT! *sploosh*
Random hot girl walking by: Aww gross... did you just shit-up?
