Youtube double take
(v.) The act of seeing something unbelievably disturbing and/or awesome on a youtube video (sometimes passing by too quickly to see clearly) and immediately rewinding to watch it again.
John did a youtube double take when he saw the newscaster get hit by a car.
Dude: Whoa! Were those jiggly boobs? *Backs video up a few seconds to watch again
