An exclamation of astonishment, originally used in "The X-Files" Episode 19 of Season 7, approximately 18 minutes into the episode.
Tech guy: "Who made this?"
Scully: "We're not sure. Either a forger by the name of Micah Hoffman, or, uh, someone else in the vicinity of Jesus Christ."
Tech guy scoffs, looking incredulously at Scully: "What?"
Scully looks at him frankly, affirming that it might be true.
Tech guy, reverently: "Buzzinga."

Adjective. Buzzinga is used by un-funny people after they tell a joke so that normal people know they are joking. Made popular by the awesome Sheldon of Big Bang Theory on CBS.
"Yeah, Miley Cyrus is totally classy.... Buzzinga."
