In warfare, a booby trap is an antipersonnel device placed in building or in a noncombat area that has a psychological draw for enemy soldiers. The term comes from the implication such a trap will be set off by a foolish person (a booby). The first use of the term is from the 1850s, when it was first used to describe practical jokes that are set off by their victim.
"Booby Trap" was the 54th episode of the science fiction television series Star Trek: The Next Generation and the sixth episode of the show's third season. It was first broadcast on October 30, 1989. In this episode, when the Federation Starship USS Enterprise discovers a trapped centuries-old alien battlecruiser it is caught in the same snare.
