"NID" stands for "Narcissist
Individualist Delusionalism", that usually stands for people who are completely self-centred or care almost none to others than themselves, even if they say the contrary.
Usually intended as an adjective to an
individual, rarely to a group.
(Can be used as plural as "nids").
Synonym to word like:
Narcissist, egoist, egomaniac, egocentric, braggart or boaster.
More used, usually, by people to used to describe "woke" affiliated people, but not exclusively, since it's dependant on the person.
