Be rude but polite- Try to be rude in a polite manner. Pass small cheeky comments at the person you are flirting with. Do not overdo it & try to have some fun doing it.

Confidence is the key- It's all about the confidence. If you do not have the confidence never try to flirt. First impression is the last impression therefore lack of self confidence can lead to a bad impression on the person you are flirting with.

Body language- This is of great importance if you want to master the art of flirting. Most people think body language does not matter but it reveals a lot about you. Try to appear friendly & welcoming. Always make eye contact & stand with solid posture.

Keep it interesting- Always start a conversation with a common topic but never keep it too long as long conversations are known to be boring most of the times. Try to bring up issues about current topics and find out the person's view on it.

Play hard to get- Do not answer the other person's question directly. Try to answer a question with a question. People often become more interested when they cannot get something easily.

Treat them mean to keep them keen- This is the most important rule of flirting. Do not be too nice in your approach. Flirting can be fun but when it comes to doing it with a stranger it can be a tough task. Once you get the "nice guy" label it's hard to keep the person's attention & you may face the risk of rejection & sometimes even embarrassment.

Now that you know all the rules of flirting go ahead and have fun. But remember not to over-do it.
