The BD refers to bondage and discipline. The SM refers to sadism and masochism (i.e., pain.) DS, the middle initials, have been "adopted" to mean domination and submission, (including power exhange.)

So anything else that would qualify as kinky sex, is only part of bdsm if done in the context of one of the above.

In my opinion of course.
That's how I understand and use the terms. If I get a kick out of pissing on someone, that's kinky, but if they're cheerfully accepting of it then it's not BDSM. That comes in if they're ordered or bound into accepting it. If they accept it freely but experience it as an awful degradation, it's on the borderline.
