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!
