I actually just picked it while I was browsing the Chart Analysis section of another forum and every thread in that section ended with this word (eg. Rihanna: The "Loud" Era" so yeah BUT it since became my online identity and I love it! It's simple yet something that can't be bound to one particular meaning or definition.
I picked mine in a rush because I was afraid registration would close again Kelly is my ultimate fave though, but I would probably have picked a prettier name if I had some time to think about it.
