In my native language Swedish we say that a person is "tvär" if he is diffcult to agree with. It literally means "blocker" i.e. tvär would mean "på tvären" (on the crossway) that means that the person is very difficult or impossible to agree with.

Well, some of these comments, well, they got me quite crossways. But the sun is quite kind. – RegDwigнt♦ Jul 28 '15 at 13:21

@RegDwigнt it's for people like you, we keep it turned on... – mplungjan Jul 28 '15 at 13:27
I'd say such a person is disagreeable. They may argue against you out of spite, just for the sake of disagreeing.
