Biting his lip could be a sign of nervousness, attraction, or anticipation. It can be a subconscious gesture indicating that he is feeling self-conscious or sexually interested in the girl he is talking to.
Stop talking.

She's either concentrating, is nervous, or is teasing you.
They're playing with you. Play back.
he wants to kiss you ;* no joke, I really think so...but I'm a girl (: And if he bites his lip, that's a plus! go get 'em girl! ;D bahaha
"Don't give me any of your lip" means not to talk back. Usually in a child, back-talking to there parents. There parents might say "Don't give me any of your lip!" :)
It means she likes you! Any other detailed answer?
It seems like more than flirting to me. He sounds like a little player. Can you explain it clearly..
More or less practicing or acting what one believes, as opposed to lip service or Talking the Talk.
It can sometimes mean you have bitten your lip.
