We got nick names at schools which kinda stuck:

Chris White was "Chalky"

I went from "Kitty" to "Cat" when I went to college.

My brother is "Petty" because our surname is Pettigrew.

One friend was called "Shakey" because her surname was Tremble

And a lad in our form was called "Stinky" well, because he smelled. As we all grew up the names stuck and we have all sat down over a pint and laugh about it. We went through a phase at orchestra by calling every one by their surnames!
