When someone walks their dog, but does not bring a bag with which to clean up the poop, and has to flee the scene.

Having no intention of cleaning up after your dog.
Friend: "Man, that dude's dog just shit in my yard and he didn't clean it up!"

Me: "Oh! It was a shit and run!"

Get the Shit and run mug.
Taking a dump at work in another department's bathroom and leaving before anyone recognizes you.

Get the Shit and run mug.
To break wind in a busy/crowded place ie. supermarket aisle, pub bar, wedding and quickly leave the scene of the crime so that somebody else takes the blame.
Man - "After that biryani last night my guts are in bits."

Wife - "Tell me about it, I had to shit and run at our Becky's wedding this morning!"

Man - "That was you? I thought the vicar had dropped his guts!"

Wife - "Mission completed then!"

Get the A shit and run mug.
Like a hit and run but involving taking a shit. It's any shit that is performed in under two minutes, thus leaving no time to wipe, wash your hands, or flush. So you drop trow, shit, pull up, and go. The next person into the stall knows they've been the victim of the shit and run.
Shit Sergeant: "Alright maggots we're doing the two minute drill, the shit and run on my whistle!!"

Get the shit and run mug.
Taking a massive, hellacious dump in someone else's bathroom (especially a stranger/acquaintance), then leaving swiftly and pretending that nothing happened.
Person 1: Hey man, why are you in such a hurry? We just got here ten minutes ago?

Person 2: Get your coat. I just took a massive shit in this dude's bathroom, and I want to get the hell out of here before he finds out it was me.

Person 1: So...shit-and-run?

Person 2: Exactly.

This is a prank only pulled off by the professionals including my friend Darren. If you are getting a ride from anyone that you dont like or dont know, for example a taxi, then you calmy pull down your pants and take a shit in the back seat. As the smell reaches the driver's nose he will mostly likely turn around thinking what the fuck is that smell?? Then you yell o fuck watch out! This is best done at nighttime because the driver would probably slam the brakes. When the car stops you get out and run.
"Man Darren, that was smooth performing a shit and run in the back of Matt's car without using any T.P."

"Give that taxi driver a shit and run so you dont have to pay for the fare"
