The person who brings their three dogs to the party, and would bring your cat if the host would have allowed it(they're allergic). And lets them go play in the yard and you sit outside the whole night, showing everyone every single of your thousands pictures of animals. In a bright outfit with pictures of your animals pasted all over. And then when even you get bored of the animals. You go inside and have wicked dance moves.
