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.

The Nostalgia Critic shouting DOOOOR from his review of Signs, a drawn out comedic yell used for dramatic entrances and over the top reactions online.
This clip captures the Nostalgia Critic stretching a single word into a long, theatrical shout of DOOOOR. The delivery starts forceful and keeps rising, turning an ordinary door reference from his Signs review into pure exaggeration. The humor comes from how long he holds the vowel and how seriously he commits to such a minor moment. It lands as instant melodrama, making the listener picture a character bursting through a doorway or demanding attention in the most dramatic way possible rather than just saying the word normally.
