Usually the final result of consuming any meal from McDonald's... explosive diarrhea. First you'll feel the side effects of the McHangover, and when you do, make sure you find your way to the nearest restroom because you have about five minutes before you start to piss fire out of your ass.
Gary: "Hey Ronald, want me to grab you anything from McDonalds?"

Ronald: "Fuck no, I'd rather not have a McBlowout today."

Gary: "What's that?"

Ronald: "Call me fifteen minutes after you finish your McGarbage and let me know how your bowels feel."
