>>11800856its hard to define.
to say something is "based", means you think it is based on /pol/'s far-right ethno-nationalism or that it reflects something along those lines.
for instance, jews can never be based, nor anything jews do can be based, for they are our worst enemies and all their shit is retarded, fake, and gay and diametrically opposed to anything good/based.
some ppl think based is just another word for cool but its not, it's a type of cool only used in context of being aligned with far-right ethnonationalism.
so if your actions, pics, humor, whatever is aligned with /pol/'s sense of being far-right, then you can say it is based, as in "based on /pol/'s far-right consensus and / or in line with such concepts"
okay?
you will see ppl using the word incorrectly, pretending or thinking that it means something like "tough/cool/chad" but they are WRONG.
