It's all up to you. You can always try pulling up some baby name's with meanings attached and name it that way, or you can name them after characters in books and movies etc. You can also look up things in foreign languages, for example, my IJCP female's name means turtle in japanese..she has a marking on her head that looks like a turtle.

There are also a ton of python's out there named Monty, btw As for some sily names, I know somebody who named their bp Soccer.

Heck, most of my tarantula's have names other than the latin, usually rather silly ones.
