Use your Android as a yellow, or red card!
If your friend says something silly? Just give him/her a yellow card. Next time a red one.
This application is really simple, you can only "turn" your mobile into a card. Hence it does not go to the internet, or suck out your phone numbers.
It's safe, fun. Take it, use it, love it.
