What are some ways to make clear your attraction in a funny/cocky way?

For example, saying "Thanks, babe" to a girl you're not currently dating/plating. I'd make it clear that I do not care what they think about the words I choose, I think coming off over-confident helps sometimes.

I'm poor at flirting, but here I think is a starting point. What are some sentences you'd use/ways to speak to girls like this?
