A type of marsupial that pretends to eat eucalyptus leaves. The truth, however, is that these leaves are almost nutritionally useless, and that the ebil koalas must resort to fiery warfare ending in bloody cannibalistic feasts upon scorched koala flesh that last centuries. In spite of this insanity, many people, especially female people, are fond of them.

A person who clings to the couch, gets stoned, and sleeps. Much like a koala who clings to trees, gets high off the eucalyptus leaves, and sleeps most of the day.

Jane: What a koala!!
