My original issue was that the tag name "cum_drip" doesn't neatly describe its apparent intent. I believe the tag is intended for "gravity causing cum, already outside an orifice, to slide down or fall, or the evidence of such". Not all of that is "dripping" but rather cumming_to_rest.

What cum_drip's wiki says:

"dripping from, or rolling down, a surface"

That's cum sliding down a surface, extending down in a string, falling midair, and/or already landed droplets. That should describe the entire process of "cum dripping or rolling" as we may see it. "Surface" must mean an exterior surface, living or not, so not an orifice's interior.

What "drip" could conceivably mean without reading the wiki:

1. A droplet, sliding down a surface, falling midair, or not moving at all. That's a small amount. Always a droplet.

2. Dripping, as in "dribbling", droplets or a small stream issuing forth from a source.

That doesn't fit neatly with "drool" as we may see it from cum_drool.

My second issue is that we already have cum_leaking, which cum_drool should always describe. It's cum leaking from an orifice, and cum_drool and cum_leaking both use the same binary tagging logic. I had thought only one of cum_drip or cum_leaking should be used to describe the same action, but they are not mutually exclusive after all. In fact, cum_leaking probably always describes cum_drip.
