I believe the answer is:
nerd
'dweeb's kin' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for nerd that I've seen before include "Student who is ridiculed for studying excessively" , "Boring, trivia-obsessed type" , "Boringly studious person" , "One lacking social skills" , "Boring person" .)
