This is the ultimate tool for holding your brethren accountable for their manliness. Use this app to revoke their Man Card. It will post to their Facebook page, along with the reason you've provided, so that everyone can see that they are letting their father down.
Likewise, when they do something deserving of commendation, give credit where credit is due–award them their Man Card.
Now go and be vigilant in your manhood - when your actions lack strength, honor, or intelligence, you can bet that your friends will be holding you accountable!
