Nelson is far more than an wrestling move that is thousands of years old. For one, Nelson is a brutal beast of a man, secondly Nelson can be the plural name of a very, very, effeminante band that you probably still listen too, and third you can find the leg nelson in BJJ's bastard cousin Luta Livre. Team the Nelson up with his brother in arms (yes the armbar, pun intended) and you have a combination worthy of heart aching ballads for your opponent.
Check out Professor Alexandre de Souza, Luta Livre Blackbelt, crank, twist and lock the crap out of his student. Anything prettier could only be the hair and makeup of the Nelson(s) above.
