"Brutality" is one of the signature finishing callouts from the Mortal Kombat series, a long-running fighting game franchise known for dramatic match-ending voice announcements. The announcer style became familiar to players across multiple entries and spread online through gameplay montages, streamer clips and short memes. People still use this sound because it communicates instant domination in a single word. It fills a similar role to the dramatic impact of the Inception Button or the shock payoff of a FNAF Jumpscare Scream in heavily edited reaction content.
