"Daddy"?

Kyrstin
it's come to my attention that couples are calling each other "daddy" and "baby" more lately. at least that's my understanding. no judgments, but I'm just curious why this does it for some of you ladies? or why do you think you like it? personally, I can't separate "daddy" from the image of my own father so I don't quite understand the appeal. I've heard it's becoming quite popular in high schools? I'm honestly wanting to hear your opinions on this. :)
