The line comes from the Payday series, where the Bulldozer, nicknamed Dozer, is a heavily armoured special enemy players learn to fear. Short enemy callouts from the games have long been clipped and shared by players because they carry instant recognition for anyone who has survived a heist. This one works beyond the original game too, since the idea of sweeping a place clean fits raids, clean-ups and takeover moments in edits, memes and streams.
