shit-up

when a huge dump comes flying out your dunghole so fast that you are lifted off of the toilet seat

Guy: Oh shit here it comes!

'turd shoots out like a bottle rocket'
'guy's head gets stuck in ceiling'

Guy: Damn i hate doing those shit-ups.

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?

shitting up

The act of pooping while vomiting at the same time.

Eg. 1: My buddy Aaron had a stomach virus and chronic diarrhea, so he was shitting up all over the place. He didn't know either to shit or vomit in the toilet.

Eg. 2: My buddy Andy got food poisoning and ate a bran muffin, so he was shitting up all over the place.
