The sound comes from the Nostalgia Critic, the angry reviewer character played by Doug Walker, during his comedic review of the 2002 film Signs. A throwaway line about a door was performed with such stretched out intensity that viewers clipped it as a standalone reaction. It circulated on soundboards and in edited videos where an exaggerated entrance needed a vocal punch line. Its lasting appeal is simple recognition, fans know the voice instantly, while newcomers still get the joke from the sheer length and volume of the yell alone.
