What are some cool nicknames for the name Roxanne?

My friends and I have been giving some cool nicknames to each other, but none of us can think of a good one for my name. For some reason, they want a sort of instant message-worthy name; for example, my friend's name is Nem so her name is MillN.E.M. (millenium). Thus said, what are some cool names that you guys can make out of mine? I'm used to Rox & Roxy already, but I would love to see what people can come up with. If its a complicated name, please give a little summary, in case I don't get it at first (haha). Thanks in advance & best answer goes to most helpful and fun answer!
