Jenna - Wow, really? I liked the nickname Cuppycake after I heard it on this video and thought it was THE most cutest thing. I also liked it because its uncommon, in my opinion. Thats so cute that your Dad called you that too!
EDIT: This is where I heard it for the first time when I was pregnant and thought "Thats her nickname!".
