Have any cute ideas for a Facebook surname to protect my daughter's anonymity?

I’m considering setting up a FB account for my daughter, so she can keep in contact with several friends who have moved away.

I don’t want to broadcast her real last name, and am trying to think of a cool/funny last name for her to use.

Example: Her BFF is “Mary Themuffin Man.”

She wouldn’t want anything too girly, like bubbles, candycane, gumdrop, etc…

Can you jellies help me think of something?
