I believe the answer is:
nerds
(Other definitions for nerds that I've seen before include "They can be boringly studious, perhaps lacking social skills" , "Boringly studious types" , "Geeks" , "Boringly studious people" , "People considered boring because of obsessive hobbies or narrow solitary interests" .)
