shitstop

when one needs to break up their current activity for the sole purpose of defecation.
“dude, we gotta stop this jog and find some bushes for a sh-tstop. i got a growler the size and temper of grandma coming.”
when one goes to the bathroom to p-ss, but subsequently decides to take a sh-t as well. similar to a pit stop in nascar, if a driver needs to get gas, he/she might decide to change the tires as well while they’re at it.
anonymous kid a: g-d dude i got out of math cl-ss and had to take a p-ss the entire f-cking cl-ss, i felt like i was about to get a uti but i had to copy this asian chick who was rocking a h-llo kitty watch so i knew she knew her sh-t.

anonymous kid b: f-ck that cl-ss dude, math is the lesbian sister of biology, so my conservative catholic parents would never let me take it. how was that p-ss?

anonymous kid a: dude, it started out as a p-ss, but since i was already there i decided to take a sh-t stop and release the kraken on that toilet!
like a pit stop, except done when driving on the road, too far from your home restroom. typically happens on road trips, after a night of drinking, or else shortly after eating fast food.
husband and wife are driving on the highway, the husband swerves the minivan into the rest area…

wife: what are you doing?! we just ______ (ate, filled up the car with gas, etc.).

husband: sorry, gotta make a sh-t stop!
sh-tstop: noun: something you do before -n-l s-x. as in “hold on i gotta take a sh-tstop before we go any further”
