According to DD:
Nice guy:
1) Smile all the time.
2) Be very nice, cordial, and friendly. Use no sarcasm, and don't tease.
3) Act as if you really "like" the woman you're talking to... and as if you're "interested" in her.
4) Give her lots of compliments.
5) Optional: Politely say "You probably have a boyfriend, right? Can I take you out sometime?"
Doesn't that go against the whole smile = confidence, Nervous guys = don't smiles, theories that are all over this site?Bad Boy:
1) Don't smile very often.
2) Pretend that you've known her for 20 years, and that you're TOO comfortable around her. Tease her for something that no one teases her about... like the way she dresses, etc.
3) Pretend that she's interested in YOU, and has been pursuing YOU, and that you're resisting her. Make jokes about it and say things like "I just don't think things are going to work out between us".
4) Give her NO compliments of any kind. If she gives you any, say "That's a cheesy pick up line. Can't you think of something more original?"
5) Optional: Say "Hey, do you have email? Good. Write it down here..."
