BOOM HeadShot! is the catchphrase for the character FPS Doug from the internet video series Pure Pwnage. The quote has been popular on ytmnd since it's original appearance sometime in late 2005. The original scene showed Doug playing the popular FPS Counterstrike, going a bit overboard and getting excited, yelling out "BOOM Headshot" each time he killed a player in the head. This is the scene most commonly parodied on ytmnd. Sometimes, the ending scene from that episode where Doug goes on a tirade after losing is parodied.
