Roll for initiative is a standard phrase from tabletop roleplaying games, most famously Dungeons and Dragons, where players roll dice at the start of combat to decide the order in which characters act. The expression moved from game tables into video games, livestreams and online videos, where it is now used as shorthand for a fight or contest beginning. Its popularity endures because it is instantly understood by gamers and easily recognised even by people who have never played, giving any scene an immediate sense of playful competition.
