What is the best nickname that no one has

Just pick the first thing that comes to your head, for instants I'll try. Soggy Banana. There! That is the first thing that came to me. Now you try.
Answer
You could pick a name that you really like or a character you've made up or even a hobby that you like e.g I like drama so you could be Dramafreak272 or somthing like that, but Soggy Banana is also good ! Hehe :D
