SEABAG - it's a basic NAUI acronym for a buddy check prior to diving. It's a reasonable start, but that's really all it is.
It is a start as it gives a common frame of reference for communication, which as you point out is crucial to being a good buddy. The system need not be elaborate, but someone who skips something as simple as that probably won't be a good buddy to begin with. I met my dive buddy of the last 22 years 9on and off) when I helped teach his certfication course. We started with the SEABAG check before each dive and it got to the point it was automatic. The activity later was photography and that does require a different set of buddy skills, but we still did the SEABAG, if unconsciously and to define each others expectations for the dive. I was on a trip with him in SOCAL recently and we picked right up on it despite not having been diving in two years together. Like I said, it provides a common frame of reference.
