You and your close friends have an inside joke — a nickname, a meme, a funny moment — that's just yours. It's one of the best things about your group; it makes you feel like a unit. Then you used it in a bigger chat, and other people picked it up. Now everyone's using it, and it doesn't feel special anymore. Worse, the joke was originally a bit about one of your friends, who was fine with it when it was just the four of you. Now half the year is using their nickname, and they don't look fine about it at all. Something that bonded your group has slipped out and changed into something else. You're the one who let it out.
