Technobabble
From Memory Alpha, the free Star Trek reference
Technobabble is a term for an explanation for a complicated situation.
In 2369, Q goaded the senior staff of Deep Space 9, who had been unable to find the cause of a crippling power drain on the station, by saying "Picard and his lackeys would have solved all this technobabble hours ago." (DS9: "Q-Less")
In 2372, when Tom Paris and Neelix were alone together in a shuttlecraft descending to the surface of "Planet Hell", Neelix said he was unimpressed by the technobabble spouting from Tom's mouth as he completed the shuttle's log. (VOY: "Parturition")
[edit] Background
Technobabble (also known as Treknobabble) is a moniker describing the pseudo-scientific terminology of Star Trek. While the terminology itself is unavoidable, several episodes were criticized for its use as a Deus ex machina.
Among the most notorious examples of technobabble are Star Trek: Voyager's "Threshold", the baryon sweep and the Heisenberg compensator, but even famous pieces of Star Trek technology like the warp drive or phasers belong to this category.
