Post some lies, swap some Boot Camp stories, and feel free to bring in the beer from the pub. If you are a civilian, pull up a chair and join in!
And now for the earlier remark from kinako mochi
Most of the Marines I've met as a soldier have the rhetoric, but often times are really cool when they feel they can drop their guard with you. They are held to much higher physical and combat training standards than I was in the Army, and that in itself makes for a force that needs more discipline and strict regulation than one that has more lax requirements. That discipine tends to make socialization outside other fellow Marines a bit strained typically, but of course it varies from person to person. The bravado, the bonding, the extrovertedness and taste for extreme stimulation is all due to having the confidence (and to some, extended to arrogance) that being in top shape, surmounting very difficult physical and mental challenges, and the prestige of acceptance by the Marine Corps gives a person. Those that are wise enough to stay true to the creed, bearing and honor of that title will succeed in life and transition easily into society. Those who cannot, will earn the stereotypes and rancor of those that judge them on action.
Hmm...I have been described as an "atypical Marine." For the most part I was quiet and laid back (In uniform only. I'm a psychotic bastard out of it). I rarely yelled when I had to give orders unless I was VERY annoyed with my kids (I went into Boot at 27. The people I was in charge of were my kids as far as I was concerned.).
One thing that made a difference for me was my dad. He was a career AF Officer (About 27 years in and got out as a Lt. Col). But when he was out of uniform he was "dad." He taught me to keep the military and civilian aspects of my life seperate.
