Used to describe the intense feeling inside when you see: (1) someone that's really ugly; (2) someone/something you really hate or (3) something "cringe-worthy".
(1) - Boy 1 "Did you see that girls face?!"
Boy 2 "Yeah, i think I died a bit inside"

(2) - Girl 1 (looking at her timetable) "Bleh, we have German next"
- Girl 2 "Ugh, I died a bit inside"

(3) - Boy 1 "I died a bit inside when I saw a fat girl do a handstand"
