Once upon a time, I was in the US Navy.
My last name is Wagner and, to my horror, there were two others with the same last name. The default nickname for those with the last name Wagner is "Wags". Well:
"Hey Wagner." We all looked up.
"Hey Wags." We all looked up.
So, finally, and since I was the only female in this little group of Wagners (no relation), We had Wagz 1, Wagz A-CO and I got to be Waglmuffin.
The DJ part came later when I was asked to use my CD player to pipe in some tunes at one of our camps in Iraq.
The End
