What’s the best inside joke you’ve been a part of ?

Mine would be "The clean team" from 8th grade.. me and like 3 of my friends were outside by the playground during our mask break, and one of the really nice and innocent seeming guys was sitting in the grass. One of my friends just said- "He's so clean.." Out of the random, and we found it hilarious.. It might not make sense to you, but we called ourselves the clean team for the rest of the year lol
