If someone is parked well away from other cars and the lot is not very full, I don't see it as being douchey to take up multiple spaces. If the lot is near capacity and you're parked weird*, then, yeah, you're a douchebag.
IMNSHO, taking up more than two spaces, even if parking in the middle of nowhere, is the penultimate in parking douchebaggery. Taking a handicapped space takes the cake.
*I have seen situations where the lot was full and I had to park weird because that was all the space that was left (the preceding drivers parked weird). Looks bad when you come back out and there are no cars nearby.
