Does That Make Me Da Queen?

So, I'm looking through my son Seth's yearbook today. He's a Sophomore and evidently earlier this year one of his friends who's graduating gave him a nickname. I chuckled when I heard it because it was kinda fitting, somehow, in a weird way. But I never thought much more of it. Almost everyone who signed his yearbook called him by the nickname Jason gave him: Baby Sef da Prince. How did my little Bubba...my Tyke-a-Roo...my Sethmeister...my Bubbaganoosh...my little Sether ...become Baby Sef da Prince!?
