McDump 

An epic, and even violent doody event (anal explosion), after the consumption of McDonald's, or "Mickey Ds". It usually happens 1/2 hour to an hour after indulging in the omni-present Scottish cuisine. It gives no warning, and may render an unsuspecting individual with a STANK- ASS, and messy drawers! Big Macs are notorious for such an event.

Yo son, I just took the most stank-ass McDump after eating two quarter pounders, fries, a shake, and an apple pie. It was nasty yo, and cleared out the public restroom!"

McDump 

The unpleasant bowel movement that occurs within an hour of eating at a certain fast food restaurant. Most food takes roughly 4 hours to digest, but this biological puzzler takes less than an hour.

Just like clockwork, I had to take a McDump 15 minutes after I left the restaurant.

Big Fag McDump-on-ma-chest

The true author of Sun tzu's art of war. Also invented the boston steamer however that was earlier in his career and he did not take credit, claiming the inspiration came from his name. Sun Tzu was a peasant he paid to put his name on the book so it would sell better, unfortunately while it made him rich this move allowed history to forget him.
