The act of taking a large shit, most commonly in a public toilet, and leaving without flushing.
I walked into the stall and there was a fatty shit just sitting there looking up at me. Somebody pulled a dump and run.

Get the Dump and Run mug.
A Dump and Run is an act where a man, pulls out (from the anus, and or vagina) with his penis partway through intercourse on the night he plans to end a relationship. At this point he should have a doozer, also known as a load of poop, ready to exit his rectum. He then pushes her down, poops on her chest, backhands the girl, and runs out her front door streaking, laughing hysterically.
