Nicknames you have, why do you have them

I can only really think of a few from the top of my head.

1. Earok I don't really need to go into this again.
2. Ewok Which was given to me by my parents, presumably because it sounds similar. Also maybe because I'm short and fuzzy (Though I probably didn't have much facial hair as a five year old).
3. Biggie / Big E / Biggie Smalls / The Bigster etc Which was given to me by an old mate (Because I'm big, and my name starts with E, hur hur) and the countless variations are used at work. I actually considered ditching Earok for one of these variations but I think I changed my mind after considering the possible legal action from the estate of Notorious B.I.G.

Note - on a completely unrelated topic, I've streamlined the look of the site a bit better. Check it out.
