Lets see.
When I first went to high school my class teacher (yes, the TEACHER), started referring to me as the Cookie Monster. Both to me and other classes, I was quite lucky though, she called someone else Jabba.
When the first Harry Potter film came out everyone started calling me Harry (I have a lightning bolt shaped scar on my forehead, more than a little unfortunate).
Then a few months after that someone called me Spadeface. Mercifully the face part got dropped but SPADE has stuck with me for a good eight years now.
So much so that on my first day at Uni, I was all set to be Jon again when a man I already knew from cycling spotted me and belted out SPAAAADE across the campus. Bastard.
