"Zuul, motherfucker, Zuul!" is a phrase used in the popular webshow, The Nostalgia Critic. Each time a demonic being appears, the Critic would utter the phrase in a low pitch voice.

Origin

It's a variation of the phrase, "There is no Dana, only Zuul." It comes from the 1984 comedy film Ghostbusters in which Dana Barrett (played by Sigourney Weaver) is possessed by the Gatekeeper Zuul.

The Nostalgia Critic

The phrase was first heard in his review of the TV series, Gargoyles.

This became a running gag in the series, in which he would say the line every time a ghost or a monster appears. Sometimes, whenever a character escapes the being's grasp, he would say "Zuul, motherfu-HEY!" In his Alone in the Dark review, he said the phrase half-heartedly, as if the monster just didn't care anymore.
