Otter: Gay male that shaves their whole body; usually muscular/masculine
Not to be contrary, but that's almost the exact opposite of what an otter is. Otters are hairy gay men who are too small/slender to be bears.
Speaking of bears,
Polar bear: a bear who has grey or white hair.
Grizzly bear: some variety of use in this one, but usually either an older or exceptionally outdoorsy bear.
Black bear: what it sounds like. A black guy who is a bear.
Panda bear: an Asian bear.
Goldilocks: basically a straight woman who spends a lot of her social life with/around bears. It's the bear equivalent of a "f** hag".
