The line comes from Dwayne 'The Rock' Johnson's WWE wrestling promos during the Attitude Era of the late 1990s and early 2000s, when 'Shut up, bitch!' became one of his trademark crowd taunts. This clean version trims the profanity, leaving just the 'Shut up!' so it can be used in family-friendly videos and streams. The clip spread through early internet soundboards and meme pages, and it stuck around because the delivery is so iconic. Today it lives on as a go-to reaction sound for shutting down jokes, rants and bad takes.
