old nick from a band i was in. i lack the ability to not fool around on my guitar during breaks between practice. they had it made into a label and put it on my guitar case. it's a lame nickname, but a fine internet handle.
i also get called 'dekken'. i think it's a play off 'dokken', who was a band i was keen on in the 80s. also a lame nick, but a fine WoW name.
'derek' doesn't lend itself to snappy alterations. 'dekken,' however, will come in handy if GH ever decides to become a norwegian death metal act.
