2. To stop off at a relative or friends house with the sole intention of taking a quick shit and then continuing on your way.
3. To intentionally take a shit somewhere inappropriate as a joke and run off. I.E. in your friends car, in the house of someone you hate, a taxi cab a Subway train etc...
4. When your stomach bubbles but you haven't shit for a while so the first portion is a super solid constipated chunk, but is immediately followed up by the nastiest case of the runs you have ever had. (think Southpark Episode of Petite Turrets - Where the guy with turrets says "Piss Coming out My Ass") Usually experienced after eating super spicy food such as Mexican or Hot Thai or Hot Chinese food with the little red peppers.
1. "Eewww. I saw that dud take a shit n run without washing his hands, now he's over there stuffing his face with the bread rolls and touching his girlfriends face. If she only knew."
2. "Sorry I had to pull a shit and Run bro, but I my stomach's aching and we were in the neighborhood so... Anyway don't go in there for at least 20 minutes"

Dan "dude that's fucked up, it had to be nasty, I'll bet he just threw the whole bag away"
John "He had too, we all got detention, but everybody thought it was worth it except for a few of the girls"
4. "Dude I had the worst case of Shit & Run the other night, totally reminded me of the South Park episode where Cartmen pretended to have turrets syndrom.. PISS Coming Out My AaaaaSSSSSS."
