The Big power allows you to send a big smiley in the chat.
When Big is enabled, and you send a message that contains one smiley and no other text or smilies, it will be enlarged. If the message contains any text, or another smiley, it will be unaffected by Big.
Note: Big and Size cannot be used together.
