Mood simply reflects our state of mind. It is probably one of the most vocal aspects of human behavior that can help one judge whether the person is game for something or not. Chat messengers started Emoticons which helped people to convey how they feel during text conversations.
The Mood Bottle Openers will do the same task in your kitchen. The bottle openers come in set of 3, each having Crazy, Happy and Shocked expressions on them.

Poketo sells a single unit for $14 and a set of 3 for a discounted price of $40.
