A dorky or nerdy person.

A phrase to describe someone who is cognitively degenerating. Synonym of "going off the deep end". Can have varying degrees of severity.

Reference to the song "Hey You" by Pink Floyd. The line "and the worms ate into his brain" makes no sense in an otherwise linear and literal narration throughout the lyrics.

A person regarded as physically and socially awkward and has little confidence, sometimes they're just plain foolish, often on account of being overly studious.

By looking between all of these definitions, we realise that the word 'dweeb' translates more or less to 'loser'

Different then nerd, geek, or dork. A dweeb is someone who is intellectual and socially-inept, but also ineffectual and devoid of passion.

An awkward, ineffectual person; specifically connotes physical inadequacy

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.
