Klingon (language)

One of the women in Howie Spragg's room on the God Complex which held the Minotaur mockingly asked Howie, "What's 'loser' in K-K-K-Klingon?" (TV: The God Complex)

Behind the scenes
Though The God Complex doesn't make a direct connection, this is an obvious reference to the language of the Klingons, a race from the Federation universe in Doctor Who related media as well as other media in the Star Trek franchise which falls outside what this wiki covers.
