The Law of Ass Eating Conservation

The universal scientific law which states that for every ass-eater, there must be an accompanying ass-eatee to maintain the balance between both sides of the ass-eating spectrum. For every person who claims to be both, there must also exist a person that claims to be neither. Similar to Newton’s Law of Equal and Opposite Reactions.

Person 1: Dude I absolutely love eating ass, what about you?
Person 2: Actually, I enjoy getting my ass eaten, which means the two of us successfully satisfy the Law of Ass Eating Conservation
