Even though I can't stand him (out of the ring, anyways), I'm going to go with Carl 'the Cobra' Froch. The reason I think it's such a great nickname is that I feel he really does fight like a snake. The way he sways his arm out infront of him and he's able to fight really long.
Carl "The Cobra" Froch was born in the year of the snake, which by the way 2013 also is. http://en.wikipedia.org/wiki/Snake_(zodiac)
Pretty boy, dingaling, and quiet man are not good names for boxers.... They are names a 3-year old girl would call her boxer-doll. SOCK.. or is it SOG (potato potato).. is something someone on the street holding a sign that reads "the End is Neigh!" would name a boxer.. just rather ******ed name for a fighter. The cobra is good! Viking Warrior is good! The executioner is good. Dr Steelhammer is good. Light out is good (although I think Toney is a moron) Dr Ironfist is also cool (and it sounds even cooler in German) Hitman is good. Although I never felt Hatton belonged among the people fit to wear that name. Sugar is also good. Again, I'm not sure Mosley is really on the level with the other Sugars...
