My dad called me SlowPoke. When I was a teenager, my friends called me Rocky. (or 98 pounds of fightin' fury)
Beebs or Beebee
Mine was ba<x>sed on my last name. I'll give you the shortened form - Schnitzel - and that was when they liked me - when they were angry with me I was Shitzel!
Smel < still is that today
Big bird but later on in high school, Kai :)
"Tiger" because of black eyes mainly from basketball (whacked by an elbow) and squash play (whacked by a wooden racket) and boxing (whacked by a gloved fist) a couple of fights outside the ring (whacked by stupidity).
