Jesus H. Christ?

What the hell does the "H." stand for? Just one of the few things that have been on my mind. I think I recently watched a movie that someone within said "Jesus H. Christ!" and was deeply concerned that I was an idiot . . . Then again, I've always been a little bit off. So, music saved/is saving my life and new women. It's surprisingly refreshing to talk to females that don't have their head so far up their own butts that they can't see the sunlight or smell their own shit.
