X-Ray’s nickname is Pig Latin for Rex.

Here are the rules for this interesting schoolboy slang.

1. Move the first letter of the word to the end.
2. Add –ay to the end of the word.

For example..
Othingnay.
Istermay Onnorcay.

3. If you can’t do this, you should move an extra letter to the back

For example…
Nglisheay doesn’t really work.
Glishenay is better.

Avehay unfay ithway tiay.
