Phantom Hieves Moment

An inside joke within a group that everyone but a single person understands. This joke is never elaborated on to this single person, and they are left in eternal confusion.

Person 1: "Her ass is not painting."
Person 2: "...What?"
Person 1: "So as I was saying about the game..."
Person 2: "No, no, no what the fuck was that?"
Person 3: "It's a Phantom Hieves Moment."
Person 2: "What?"
Person 1: "Don't worry about it."
