Get the McShit mug.
The substance that exits one's arse a few hours after eating McDonalds. Think 'McFlurry', imagine it brown in colour, with the same texture but different ingredients and that is the McShit.

A horrible, bug-invested fast food restaurant that serves Big Macs, Quarter Pounders w/ Cheese, and McNuggets. Run by retards.
I used to work at this one place. It had bugs, burgers, and retards there.
Oh, you mean McShits?

An agressive shit-shake in the toilet after going on a McBinge. Will generally have the bathroom smelling of a Happy Meal when finished.
