Well, contrary to the belief my s/n is related to the Duke, I actually got this nickname from playing RISK with childhood friends. If at anytime during the game that I was wronged, or concluded that winning was not probable, I would basically try to take anyone and everyone I could down with me. In essence, I would "Nuke" the board. They started calling me Nukem when we played and it just kinda carried over to online play as it became available.
