A word used when you agree with something; or when you want to recognize someone for being themselves, i.e. courageous and unique or not caring what others think. Especially common in online political
slang.
The opposite of
cringe, some times the opposite of biased.
The latter usage is the original use as coined by
rapper Lil B, and the word originally took off on the meta-ironic website 4Chan with the latter meaning. For that reason the word is largely used meta-ironically (without context you can't tell if it's being used ironically or sincerely as it's used in both ways) and was popularized in online political
slang of conservatives and the political right before being adopted into mainstream online political
slang (likely through shitposting websites or subreddits such as r/politicalcompass memes that are similar to 4chan in their meta-
irony and "edginess" but contain a wider variety of political beliefs) and eventually adopted into general online vernacular.
When used in online political language it can
mean "based in fact" or the opposite of biased due to the number of
people who saw it being first used seriously by the online political right and came to the conclusion that is was related to the phrase "destroyed with facts and
logic" in reference to right wing personality Ben Shapiro.
