What is, and how do you flirt?

So, I have never flirted with someone and I am not entirely sure as to what it actually is. Is flirting just complimenting someone else, is it sexual innuendos, is it both?

And how would you flirt with someone and not be awkward? I personally can't even imagine complimenting a girl without feeling slightly awkward about it because I don't think she would want one from me at least.

Yes, I am bad at being a social person.
