Do we provide a chance for others if we respond flirtatious joke with flirtatious joke?

It’s usual if we hear someone says “Hey baby,I’m single” or “Hi honey,wanna hangout with this handsome guy?” or ” I got a ‘big’ one”
We know they’re all flirtatious jokes and we can also respond with flirtatious answer but does it means we give them a chance to approach us/invite them for close relationship?
I know this could be differ from one person to another but I’m saying this in the context of good-looking stranger.

I usually silly enough to respond to these jokes with flirtatious answer (provided the one who say that is attractive enough) even though I don’t take it as serious matter. I ignore those who say in degrading manner.
