a cross between shittin yourself and a fart.

When one goes to fart, but shits themselves in it's place.

Get the shart neck gaiter and mug.
when one feels a fart coming about, and then lets loose and some shit comes out with it. one may make a disgruntled face, or sometimes a groaning/grunting noise. otherwise, then one waddles back to ones house because of amount of shit in ones pants, it looks something of a waddling, zombie type walk.
dude lets go. wait. what? damn, i just sharted.

A surprising expulsion of poop that occurs during the farting process
Jane and I were napping together after filling ourselves with bean burritos and getting drunk off beer earlier in the day at El Charro’s. We were supposed to meet my parents for dinner at 7:30, and I didn’t want to not show up because first of all my parents generally have a big stick up their asses and second they wanted to meet Jane for the first time. The alarm was supposed to ring at six, but one of us set the damn thing incorrectly so we kept dozing until Jane snapped out of it around 7. Girls can wake you up in funny ways sometimes, and old Jane was a funny one. What she did was she climbed on top of me and sharted all over my face. I knew she meant to fart, so I wasn’t mad.
