look up any word, like jamflex:
when a player on a Call of Duty game, namely Modern Warfare 2 or Black Ops, uses the perks Marathon and Lightweight Pro to speed from their spawn to the enemies and quickly kill everyone.
Player 1: "Dude, we just got wrecked!"
Player 2: "Yeah, man alright here's the plan, we marathon lightweight it this time."
