It’s a usage, in other words, that is exceptionally bloggy and aggressively casual and implicitly ironic. And also highly adaptable. Carey has unearthed instances of the “because-noun” construction with the noun in question being, among other terms, “science, math, people, art, reasons, comedy, bacon, ineptitude, fun, patriarchy, politics, school, intersectionality, and winner.” (Intersectionality! Because THEORY. Bacon! Because BACON.)
But the formulation isn’t simply limited to nouns.
