In the Xbox 360 video game Gears of War, this describes the act of going into the Rhody Run (hold A and you run faster and are followed by a shaky cam) with your shotgun out until your right in front of an enemy, at which point while still in the run, effectively blowing him into chunks. It's super awesome.
"Oh dude you just owned Poindexter666 with that scoot and shoot! You ran right at him and he missed. What a noob!"
