Overheard-Two sons

For the last two years, I've called Tayvin bubba-louie. I've always referred to it as a nickname but I guess it's more of a term of endearment because today I called Tahnyon bubba-louie. So I asked Tayvin if it's ok for me to have two bubba-louies. His response: "Yah, I guess so cause you already bought two. And once you have two sons, you can't sell 'em back."
