I used to play football - was a Defensive Tackle.
I played with a reckless abandon - throwing my body all over the place. On third downs I would come up to the line of scrimmage and growl (like a dog), hoof at the ground (like a bull about to charge), beat my chest (like a gorilla), or roar (like a lion).
It was generally accepted that I was, at least, half-crazy (like, for real).
My last name is Van Sant (Dutch, 2 words - go figure). So, they began calling me "Van-Zilla" (half Van Sant - half Godzilla).
Long story short - I gave up the game of football - but kept the nickname .. have used it ever since.
