I'm here to announce my departure from hearing your dumbass comments as I'm about to block you because I can't stand seeing people trying to continue normalizing the use of the word based.
It's fucking stupid ... There's a story about.it originating with an obscure ass rapper a few years back but I don't buy that... It's really from reddit, absolutely right wing, and completely stupid as fuck.
It absolutely was repopularised by Lil B, I was there for it. My understanding at the time was that it was a reclamation of the word from an original slang meaning of being strung out on crack. Lil B was celebrated ironically by the 4channers that later propagated the right wing appropriation of the term. I always interpreted that to refer to being strung out on 'the red pill' i.e. being unapologetically fascist.
I don't know anything about the origin of the new use of 'cap'. No one was saying 'based' in proto-internet culture before Lil B's music videos around 2010-2011. This guy blew up quick and he used the word in his nickname. It was his version of BRRRR for Gucci, FLOCKA, etc. That's just a fact.
At least base your distaste on reality. The term was born on 4chan back when it had a mostly leftist penchant (around the time the OWS movement was going off). It has nothing to do with "right wing", that's just you putting political polarization on everything.
