The boop clip comes from Lúcio, a playable support hero in Blizzard Entertainment’s Overwatch, released in 2016. The character uses sonic technology and has an upbeat, music-driven identity, making the short line closely associated with his playful knockback moments. Players repeated it in gameplay videos, highlight reels, streams, and fan animations, helping “boop” become recognizable beyond a single match. It remains useful because its instant delivery fits precise edits and communicates a light push or interruption without requiring additional context.
