When one goes to the bathroom to piss, but subsequently decides to take a shit 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: God dude I got out of Math class and had to take a piss the entire fucking class, I felt like I was about to get a UTI but I had to copy this Asian chick who was rocking a Hello Kitty watch so I knew she knew her shit.

Anonymous kid B: Fuck that class dude, math is the lesbian sister of biology, so my conservative catholic parents would never let me take it. How was that piss?

Anonymous kid A: Dude, it started out as a piss, but since I was already there I decided to take a shit 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 shit stop!

Finding yourself out of the vacinity of a toilet and just letting nature take its course and emptying your bowels in your pants.

Might be due to eating a dodgy lamb salad and drinking too much stella the night before and having a bit of a dicky stomach
Michael: So I was on my annual shop to Wilkinsons to pick up toothpaste and new shoe laces as a replacement for a belt for my trousers.
Anyways my stomach was playing up.
I Was walking home and I felt my arse twitch like a rabbits nose.
I went to let out a fart but I felt a warm sensation run down my legs. And I tried to retract it back up my A hole. Unfortunately I had shit stains on the back of my jeans. Tried to ignore it and walk home. Few minutes later, I had the same feeling but this time I didn't even try to hold it in. I just took a SHIT STOP and let the chocolate niagra falls fill my pants. It had seeped in to my shoes and everything. I had Squidgy feet the rest of the way home. I got home and just peeled off my rusty jeans at the bottom of the stairs and jumped in to the bath. It was like a scene from Charlie and the Chocolate factory when Augustus Gloop falls in the chocolate River
