more than just a screen name

I got my nick when I was 18...
I played in Hamburg in an American Football Club. At this time I reached the 2-meter-mark, and in 1981 that was really tall. And I had roundabout 130 kg ( 290 lbs ) of weight...
One day we played against another team, their coach told one player he should tackle me - the guy looked up and cried: This guy is big and bad!
So, next play my coach changed my name at the shirt to "big&bad" - and I kept it for my life...
