On Becoming A Grandmother

My husband and I were in the kitchen this morning talking while getting breakfast ready.  Somehow, we got on the topic of becoming grandparents. (For the record, we are too young to be grandparents, and are not expecting any in the near future. At least for another ten years.)
So I tell my husband that I am looking forward to becoming a grandmother, but I don't want to be called "Grammy". Nor do I want to be "Nana", "Ma", "Mama" or "Mummum" (that's what the children call my mother).
It seems as if the first grandchild names the grandparents. Usually, they try to find a name that distinguishes each grandparent from the other that is also easy for them to say. I will not allow that! They will not name me "Moomoo" or "Meemaw" or "Gammy" just because they can't speak proper English.  I will NOT accept it!
So I thought about it for a while and I've come up with  the following options:

1. "Sasha Fierce" but quickly changed my mind after reading on the history of that name.
2. "Birdie" because it gives the impression that I'm skinny and demure.
3. "Diva" because I want to be the sexy grandmother. 

Whatever name is chosen, it will be on MY terms.  I don't care how sweet and cute and cuddly they turn out to be.


So, if you are a grandmother, what do they call you?  Or, if you're like me, what would you like to be called? I know that I have a while before this is relevant for me, but it's always good to be prepared, don't you think?
