So nice that you ask!
On a german cosplay-page i am called "Hirsch" which translates to "deer". I choose the name because my best friend is called "Koenig" (german for "king") and both of us wear a "crown" now :-3 It's a reference to the marauders from Harry Potter.
Moreover: my are initials "M" and "D" so it fits perfectly ;-D
