I wasn't military, so I don't have an opinion to throw in on the legitimacy of the guy. But if he does happen to be an actual marine, I wouldn't give a SHIT what he does to unwind at a party. If I'm so adamant about being given pretty much unrestricted freedom in my civilian life, I would expect that somebody who's serving his country and offering to risk his life in that capacity deserves to pursue R&R in any way he sees fit. I've been close friends with several marines over the years, and never knew a one who didn't have some insane party stories.
