If you're scratching the back of your leg, it means you are nervous because you are in the presence of someone who is very attractive that you like a lot.
I was on a date with this girl the other night and she couldn't stop scratching the back of her leg; she likes me a lot.

Girl: I don't know why my leg is so itchy.

Guy: Oh I heard that scratching the back of your leg means that your nervous or something. And that your with someone you like a lot.

Girl: Well that explains it!
