How do you guys respond when a girl’s opener is something like “hey daddy” or “sup sexy?”

for the hey daddy one, it’s more forward, so i responded with “only good girls get to call me daddy and they have to earn it”

she responded right back asking how she can earn it, so that went well. what do you guys do?

then for sup sexy, it’s a little more playful but still sexual. i don’t know whether to match the energy or stay nonchalant. wouldn’t a man who gets called sexy all the time just remain chill about it? but at the same time i feel like it deserves recognition or a reward. what would you do?
