This sounds exactly like a guy I went to college with, back east. He's actually quite smart, but is a habitual exaggerator, if it's not an outright lie. His first impression is always positive to folks who just meet him, so he actually does get some interesting opportunities quite often, but he can never make much out of them because of oral diarrhea. It's always just a matter of time with people like that... I'm certain my old classmate has a personality disorder. Absolutely positive.
