This is when two guys are dutch ruddered by a chick until similtaniously ramming their cocks into her mouth and 'releasing hell' or otherwise refered to as ejaculating into her gullet. It simulates rowing on the warships, being driven by the rowing master until the climax of ramming the enemy.
Guy one: "Dude, that girl just got a new definition of Roman Warfare. So much for her history major in Roman Warships!"
Guy two: "Agreed. The emperor himself would have given battle honors for that show!"
