Butter

A lonely obese boy everyone calls "Butter" is about to make history. He is going to eat himself to death-live on the Internet-and everyone is invited to watch. When he first makes the announcement online to his classmates, Butter expects pity, insults, and possibly sheer indifference. What he gets are morbid cheerleaders rallying around his deadly plan. Yet as their dark encouragement grows, it begins to feel a lot like popularity. And that feels good. (imdb)
