A nice thong you're wearing??!? I thought that you wanted a date, not a slap in the face.
Try: Movie X just came out and I was hoping to see it Friday night.
<Pause to see if she's heard of it, seen it yet, what she thinks of it>
If she's seen it - suggest going out to lunch to talk about it.
If she hasn't ask her if she wants to go with you.
Simple, elegant and two fringe benefits.
1) The movie will cover uncomfortable silences - you're not expected to talk during a movie and you can just get acclimatized to each others presence. *putting a silencer on the nervousness*
2) You do have something to talk about AFTER the movie..and conversation, more than anything else, will take a first date and help turn it into a second date.
