Brian went to school at Oklahoma University, whose mascots are horses named Boomer & Sooner. So, years before kids we talked about having kids whose nicknames would be Boomer and Sooner. In August on our vacation Brian mentioned that we had three kids now and none of them had those nicknames.
So that night around the camfire I looked over at Mulu and said "hey - you look like a good "Boomer" - from now on instead of calling you Mulu, we will call you Boomer."
He thought for a moment and said "no - I don't like Boomer" pause - - - "but you could call me wiener"
