LOL...what a question anyways......If you're just talking to random women trying to know if they like you or not. Just smile, ask them open ended questions about themselves. If it looks good ask for their phone number. Once on the date don't touch them, let them chase you which drives them up the wall a lot of times. Don't talk about yourself, sex, etc. Keep conversation focused on them and just keep smiling (not cheezily). Compliment her in a honest, and witty way. There's a fine line between flirty and being annoying and creepy. Probably what every girl/guy considers good flirting is different. I agree there's a bit of teasing and a bit of innuendo, a bit of touching and a lot of laughing. personally i think it's about getting at each others vulnerabilities, that's where the teasing comes in, you're opening up to each other, trying to break down the barriers. you just start with little things like complements or sexy but not sexual comments. Honestly i'd go for a person i felt a connection with, that joking and laughing and showing how we felt about each other was natural and didnt need to be premeditated. :))
