The Olive Theory is a theory in which if one person in a relationship loves olives, and the other hates olives, the two are meant to be. (Originated from "How I Met Your Mother")
Person #1: (to significant other) "how do i know that this will last?"
Person #2: the olive theory! Do you like olives?
Person #1: i hate olives!

Person #2: i love them! We are meant to be!
