From The Rules:

"The basic principle of 3 Little Words is that ANYTHING can be described using only 3 words. For example, 'mouse hunting pet' is ... CAT! A player studies an 'answer' on the cards, and tries to describe it in only 3 words. The other players try to guess the answer. The first player to get it right wins a point, and so does the asking player. First player to 20 points wins!"
