How did you choose your RS name?

This current name I stole off a friend as a joke, it was his first name in RS but he didn't realise he could change his current name to it since the first account was banned so I took it, said hi, he raged and hasn't talked to me since :p

I won't change my name again though until I can upgrade to the one I've been watching since 2003, it disappeared from the high-scores early this year so it's only a matter of time.
