McShit 

The act of using the public restroom in a fast food restaurant without purchasing any food. When challenged by a suspicious manager, the assurance of a subsequent purchase of said fast food is known as a "McShit with Lies".

Dude, stop here, I can't hold it in anymore. I gotta go for a McShit. Meet me at the Drive-Thru in a few minutes.
