Animal can be an adjective. in-and-out, eh?
Nope, not that, actually. Is that usage ("animal style") the adjective form anyway? Someone smart answer this, please.
i think so, it might make more sense if you don't think of it in the phrase "animal style" and just placing the order "animal" - what was your context?
But I wish the public could, in the midst of its pleasures, see how blatantly it is being spoon-fed, and ask for slightly better dreams.
- Iris Barry from "The Public's Pleasure" (1926)
