Jump Scare. 1  A tactic used in horror movies to scare people, the jump scare is used by unimaginative filmmakers as a cheap method of frightening the audience; i.e, making them literally jump out of their seats.
Fare evasion and fare fraud is generally a crime in most jurisdictions. The fare not paid, compared to potential penalties and hassle, is generally considered ânot worth itâ. One method of fare evasion is jumping over the turnstiles which mark the entryway into a subway system; hence the term, âturnstile jumpingâ. Other methods include adults traveling on childrenâs tickets, or using discounted tickets or free passes that the passenger is not entitled to.
