a fuckin' jarhead that loves nothing more than the corps. he thinks, breathes, eats, masterbates to, and shits with the corps always, and i mean ALWAYS on his mind. to him, there is nothing more tasty and more satisfying than devouring a fucking MRE for breakfast. there is nothing more pleasing than the feeling after you complete a fucking 24-hour O-Course pt session with sandbags. motivators are known to enlist for 26-60 year contracts at one time without ever thinking about it twice. they are also known to use the strange, yet amusing "Oo-rah" phrase to acknowledge anything from "yes" and "no" to the common "good morning" and "i understand".

Guy: "I've heard she goes down on guys a lot. I bet she's a great oral motivator."
Guy: "Ugh she's such a slut. But really all she is is an oral motivator so she doesn't have to worry about being safe."
