When you’re sitting with two or more friends, and you and one of those friends refers to an inside joke that the others don’t understand. Kind of like the reference flying over their head without them noticing.
Person 1: “Hahaha, yeah like that night with the pumpkin and the homeless guy”
Person 2: “Yeah I remember”
Person 3: “I don’t get it”
Person 1 and 2: “We always end up with referential flyovers with you"
