If 4chan popularized it, then it wasn't rap. it was a word already, so a rapper can't invent it. And then as far as its usage, it seems to have traveled round the world and come to the dissident right through 4chan. The implication saying it was invented by a rapper is that a) it belongs to black people or b) white people got it in some kind of wigger fashion, which isn't the case. There are definitely words white people have gotten from rap in precisely that fashion. I just don't think "based" is one of them.
