Do you name your Fluther accounts randomly or are there any background stories behind you nicknames?

Why I chose my nickname “Mimishu1995”:
The name Mimishu comes from a ruler I used to buy when I was young. There was a very pretty mouse encraved on it and according to the letter written on ruler, its name seemed to be “Mimishu” (actually it was a Chinese name, and it seemed that “shu” means “rat” in Chinese). That mouse got such a good impression on me that when I created my Fluther account, with an aim to create a cool nickname, I named my account after it.
And 1995 is just my year of birth :)))

So is there any meaning behind your nicknames, or the only reason you name your account like that is because you just want a name?
