look up any word, like muddin:
 
1.
A human turd of any size / shape that has been left anywhere BUT a toilet.
The area near my building's dumpster is often used as a pit stop by the homeless. Dumping garbage late at night means I must lookout for the inevitable SHANGHAI BABY.

2.
A large fecal mass usually , but not exclusively shepherd's crook or total bowlringer shaped and a floater.
Mark had to go, and after a mighty grunt, was pleased to feel it all come out at once. Mark looked into the toilet bowl, and beheld his magnificent SHANGHAI BABY.
