What makes one girl "hot" and one gorgeous/stunning?

You hear men say all the time "Wow that chick is so hot!" Other times, you will hear them say a girl is cute or pretty. What about a womans looks determine what category she is placed in by men? I think a 'hot' woman might dress more provocativley and have a great body as opposed to her face. I have definitely heard guys call 'butterfaces' hot and I didn't get it... and a pretty girl might be more down to earth and have a better face as opposed to her body? Guys what do you think?
