We had a 'backward' kid near us when I was a kid and he played in goal whenever we played soccer on the school pitch. He once did a No.2 and shot off home . From that moment on we called him

Babapants

I knew a Mad Dog , a small guy called Time Bandit , Sea Dog , Capt Mowzer , Corky ( the dog off Vic Reeves )

Any other bizarre names ?

Sharks

Ryan Bailey is now called "Hoodie" or "Glass Jaw"

Ferocious fishes,with a long body and two dorsal fins.Rows of sharp teeth.Nicknamed Jaws.
As far as I know,they are dangerous,but not crazy.
