The phrase itself is everyday French internet slang, combining a blunt request not to be spoken to with the abbreviations stp for s'il te plaît and a sarcastic merci. As a sound, it circulates mainly as a short reaction clip on soundboards and in short-form video edits, where its brevity makes it easy to drop over a scene. Its appeal is not tied to one show or creator, but to a universally familiar feeling: wanting a conversation to stop without starting an argument, delivered with humour rather than hostility.
