The line comes from Grand Theft Auto: San Andreas, released in 2004, where Melvin 'Big Smoke' Harris shouts it after catching Carl Johnson breaking into his house. The scene became one of the game's most quoted moments, and short clips of the shout spread widely on YouTube, forums and soundboards during the 2010s. Its lasting popularity comes from how recognisable Big Smoke is as a character and how easily the warning fits any mistaken entry, surprise visit or territorial confrontation shared online.
