Different then nerd, geek, or dork. A dweeb is someone who is intellectual and socially-inept, but also ineffectual and devoid of passion.
Max, fitting the role of the dweeb, spent all Friday night reading Hartshorne's "Algebraic Geometry" while the others in the dorm wing went downtown for an evening of fun.

This word was accidentally created circa 1973 by a group of high-school students at a northern Indiana school.

The original spelling of the word was 'D-W-E-E-D' and was meant to be a shortened form of dickweed. By using the word dweed, they were able to call their classmates derogatory terms in front of teachers with no repercussions.

Because only a select group of students knew what was actually being said, the word was mispronounced in abundance, causing the word to be spoken as dweeb.
"You're such a dweed."

"I'm not a dweeb!"

This is actually an acronym for the phrase "dick with eyebrows," you dummmies. You are calling someone a walking penis.
You are all dweebs because you did not know the origins of the word you thought you were defining.
See urbtards.
