After eating a crap load of McDonalds the horrible after effect that occurs in a near by bathroom. Usually leaving the consumer incapacitated and sore.This term was coined by the brave man who starred in the movie Supersize Me!
When at McDonalds, eat all your nuggets, then put your sauces back in the box. close the top then ask if anyone wants to finish you nuggets. they will shake the box to see if there is really anything in there and get excited. Only to be McTricked when box is opened.
