McShits 

It's when you eat way too much fast food, probably McDonald's, and you get the runs.

Yo man, I got the McShits today from eating all that McDonald's.

McShitstain 

When you order a McChicken, hash brown, and a egg McMuffin and take the egg and hash brown and put it in the McChicken and eat it and it is so good it’ll leave a shitstain in your underwear.

“What did you eat at McDonald’s? “
“I had a McShitstain and it was so goodie left shitstains on my boxers!”
