What's the difference?

wats the difference between a dork, a dweeb, a nerd, and a geek? could someone make a list from best to worst. #1 being the best #4 being worst

a nerd is someone who is smart, and enjoys knowledge over his hobbies. A geek is someone who likes the same things nerds like, but doesnt prefer knowledge as much. A dweeb is a dweeb.

Dork - http://dictionary.reference.com/search?q=Dork

Dweeb - http://dictionary.reference.com/search?q=Dweeb

Nerd - http://dictionary.reference.com/search?q=Nerd

Geek - http://dictionary.reference.com/search?q=Geek

however, its different to ask 'what is the difference' in terms of 'what they mean' OR.. 'what they mean in modern slang'.. as the definitions of words change over time
