Burger King, for no good reason, has America's edgiest advertising. And it just got edgier. Now you can make it known publicly that someone's "friendship" is less valuable to you than 1/10th of a sandwich.

The grease monarch has released an "app" (APPLICATION, slang) for Facebook letting you destroy your fake "friends" and humiliate them at the same time:

The app rewards people with a coupon for BK's signature burger when they cull 10 friends. Each time a friend is excommunicated, the application sends a notification to the banished party via Facebook's news feed explaining that the user's love for the unlucky soul is less than his or her zeal for the Whopper.

Anything designed to take on the excess-Facebook-friend menace while simultaneously promoting obesity is okay with us. [Adweek]
