This event takes place when one individual pulls a "fast one" or a switch of two similar or close to identical items on another individual. It usually has to do with food items in which one food container has more food than the other. The switcher will naturally take the food container with more in it and leave the other for their associate.
Hey man, you pulled a Cincinatti Switchup for the box with more fries.
Don't try to pull a Cincinatti Switchup on me, I want the blonde and you get the brunette.
