Bear (gay slang)
Some of the more common labels for bears are Cubs, Otters, Chasers, Muscle-Bears, and Chubs. A younger (or younger looking) version of a bear is called a cub. Cubs are often younger or less mature or masculine-looking. The term is sometimes used to imply the passive partner in a relationship. An "otter" is a slimmer or less hairy bear regardless of age, and a Chaser is a member of the bear community who is attracted to any kind of bear without being one themselves.
