short for "marine boot", a very junior marine usually in transition from boot camp to MCT/ITB or fresh out of MCT/ITB and newly arrived at their new command, that run around screaming oorah, semper fi, and kill, completely fresh and clueless as to what the Marine Corps really is and are lost on how real marines actually act in the world, they are fairly entertaining to watch because they look like lost puppies wondering around doing their maroot things an aternative spelling is "marute"
New River Marine1:lets goto the MCX
New River Marine2:are you crazyyou know its Maroot Monday, all of the maroots from Geiger will be here!
Collective noun: in the army the Marmots are the platoon equivalent of the "boy named sue." Marmots travel in packs and are often seen prowling, as that is their usual mode of transportation, they can prowl by foot, car, bike, boat, tank or any other means of transport.
One would be terribly mistaken to underestimate a marmot, one cannot possibly overestimate the Marmots.
Did you see those Marmots?!?! I swear there was something between us and them.
There was, but that won't stop a Marmot on the prowl.
Death Dealer pog, "man who would want to he a marmot, out platoon name is more bad assed!"
Death Dealer grunt, "watch your mouth, they could kick your ass even if they were called the rainbow unicorns. It takes balls to carry a name like that with pride, and it takes a hell of a soldier to earn that name."
