Is nerd a good word?

Originally derogatory, the term nerd was a stereotype, but as with other pejoratives, it has been reclaimed and redefined by some as a term of pride and group identity. However, the augmentative terms, geek and dork, have not experienced a similar positive drift in meaning and usage.

What is a dumb nerd called?

Theres one more term we can add to this geeky list: dweeb. Dweeb is “wimp; a stupid or uninteresting person.”
