I see there's now a twisty_boobs tag, for when 2 neighbouring breasts (usually in mid-swing) are pointing in different directions. I think this would be better as breasts_akimbo.
Which definition of "akimbo" makes this fit? The only ones I'm aware of are the FPS "dual-wielding" akimbo, which Danbooru uses, and the hands-on-hips pose that is probably the most common use in reality.
