kexkez
The "kex" actually came from an online friend who would always mistype "kez" ( my name is kerry). You'll notice the x is next to the z on the keyboard. It became a running joke and I started answering to kex. Given that I am also a terrible typist it seemed perfectly appropriate to have a nickname that was actually a typo.
I think that's such a good backstory to your username! I wish mine actually had some meaning, i only chose wonderland coz I was listening to that John Myer song!
