A fan of a sports team only when said sports team is currently winning. Hence, a fan only when the sun is shining.
Person 1: Man the Sharks stink. They lost two in a row.

Person 2: Damn, you're such a sunshine fan Person 1. You weren't bitching a week ago.

Person 1: Crap, you're right, Person 2. I should always support my team.
