From the oxford english
Geek - a degenerate
Degenerate - having declined or deteriorated to a lower mental, physical or moral level.
Nerd - as a stereotypical or archetypal designation, refers to somebody who passionately pursues intellectual or esoteric interests - such as books and video games, rather than having a social life, participating in organized sports, or other mainstream activities.
Nerd - an unstylish, unattractive, or socially inept person; especially: one slavishly devoted to intellectual or academic pursuits.
None of the above for me, I manage to bring up two kids, study for a chemistry degree and be a full time SNCO in the British Army at 35, as well as play 40K. Many of my gaming friends are similarly well balanced members of society.
That said I still refer to the models as toy soldiers and the game as Nerdhammer so maybe?
And I don't want to stereotype but many of our younger gamers are Goths or similar and probably already qualify as nerds/geeks to the great unwashed.
