The phrase comes from bomb objective modes common in tactical shooters, where one player carries the explosive and the whole round depends on keeping track of it. Clips of players admitting they have misplaced it became a shorthand joke online, shared on soundboards and in short edits detached from any single match. Because the line explains itself without context, it spread beyond shooter communities into general fail and panic memes. It remains used because losing something vital at a critical moment is a familiar, instantly relatable mistake.
