brrrcore: the thing that goes brrr, assuming it exists, when you remove deadening constraints, complexity, ornamentation, and superfluity from a thing, and distill the rest to it’s essence. The id or kundalini of the thing. For eg, the tweet is the brrrcore of the blogpost.
Eg. a blogpost isn’t working. You throw away the headline, all the pipe laying and hedging. Unbury the lede. Then tweet it to test the brrrcore quality. Tweak and test till it goes as brrr as possible. Then add back everything you threw away.
