It stands for "doing it right"; there's a subset of divers who have the idea that there's only one way to go about diving correctly, and they have published a set of rules governing equipment and practices. Many "DIR" divers I have met have been snooty insufferable bores about it, but to be fair, I haven't met that many of them. It could every well be that I have met more of them than I realize and they just didn't make such a point of being right about everything and all the rest of us, by distinction, being all wrong. It could also be that my viewpoint has been slanted by my exposure to a few unpleasant DIR divers and the majority are fine folks.
