What is flirting?

I dont know if these makes sense. I've read lots of mytakes and articles on how to flirt but not one where it actually says what it is. Does flirting show a sign of chemistry between two people, how long should flirting last before you make a move/ask the person out? If the other person doesn't respond should you drop it or try a different tactic?

I reckon my only way of getting a boyfriend is being a bloody good flirt.
Playing games between two people
Testing the other person
A bit of fun
Nothing really, people just flirt
