I think this has been asked a few times, but here goes, I was called Ratter as a nickname by local farmers where I would hunt rats as a pest controller, the 15 came from Hotmail not allowing me to just have RATTER as an e mail addy so they stuck 15 in front of it.
It's been a nickname for years ever since my friends bf - rather worse for wear - got Helen and Gillian muddled up and we became Hellion and Gillan. And we still are, even though the bf is long gone!
oops forgot to say how i came across this name, i think i wanted to ask something that needed answering quick and this name was the first name i thought of, i don't like it, it sounds masculine but it'll do.
