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.
Jumping spiders do sometimes bite, but their venom is not considered to be dangerous (unless youâre allergic to spider bites). They are sometimes mistaken for black widow spiders, but they are far less dangerous. Jumping spiders donât hunt using webs, but they do build a web-like nest called a retreat.
