This is the true defintition:
n. a geek
with VERY little/no social life.
This word was made as another word for geek (or vice-versa) and is still used by the general public, who do not know the true meaning of the word.
Cool person- "What a Nerd! He's the biggest geek ever. He doesn't even have ONE Abercrombie shirt!!"
Geek - "I like your pc, but you need to get out more. Come join our anime club!"
Nerd- "I'm not a nerd! I'm a geek! Get over it!" *snuffle*
