The line comes from Grand Theft Auto V, identified in the clip metadata as part of Mission 58, Fresh Meat, a story mission in the game. Short voice lines from GTA V have long circulated on soundboards because the game's dialogue is quotable and instantly recognisable to players. This one survives as a compact confrontation cue: it is short enough to drop into edits, streams and reaction videos without losing its meaning. Its appeal is the directness of the warning, which fits both serious fight scenes and over-the-top meme takedowns.
