I don't know, she sounds like a pretty typical 19 yr. old to me - if anything, a little less foul-mouthed than most kids I see running around in my son's 3rd grade class.
If I had a microphone shoved in my face at any given point during the day, you'd hear a whole lot worse. I swear more when I run out of Diet Pepsi than that. Actually, I swear for no reason occasionally.
