I got that nickname in the Navy b/c I was the smallest in the machinery division (5'5" and 130lbs) but I'd wrestle/spar with anybody. 15 years in martial arts so for me it wasn't about winning or proving a point - it's just fun. Anyway, I came into work one day with my hair dyed white and they said I looked like Chickenhawk so it's stuck. For 7 years now... LOL
