Whether you like it or not, a staple of modern horror movies (and even a few not-so-scary flicks) is the jump scare. You might be familiar: the building music, the mounting tension, and then the explosive jolt of sound and movement that makes your heart skip a beat. When it comes to all the best recent horror movies and all the terrifying films on the horizon, you can bet your ass you'll encounter more than your fair share. If you look back through the years, though, it's not hard to remember all the jolts you've felt. Luckily for all of us, one YouTube video stitches together a selection of the best and jumpiest scares to date. Watch at your own risk.
