Don’t brag about other people who are into you.
It may seem like a good idea to use this approach from a reverse psychology perspective. But no one really wants to hear about other people that like you, or that may be into you. It may make them jealous or get you some attention, but it is leading the interaction with playing head games. Not a good start.
Don’t get too touchy-feely too soon.
If you are flirting with a guy, be sure to keep the physical contact on the back burner until later. This is especially true if you are out on the town. Physically flirting can indicate to a guy that you may be ready to get physical immediately. So unless that is your goal, you may want to refrain from that in the first interaction.
Don’t avoid eye contact.
Eyes are the window to the soul, and this is totally relevant when it comes to flirting. Look him directly in the eye when you two are talking. This will show him that you are interested and not afraid to connect with him. You may even just be able to read a bit more about him by making good eye contact.
