The most commonly used word for "cool" in the Esperanto language. (Language, not the GTAcar named after the language.) It's derived from "MOderna-Juna-Stilo," meaning modern youth style.
When a groupchat splits off into a smaller groupchat, excluding members that are problematic or no longer part of the friend group. More discrete than straight-up removing someone.
I knew Ben would be mad and confront us if we removed him from the groupchat, so we had a groupchat mitosis!
