I propose the following cards for men to give to women:
Green card: THANK YOU!
The person who handed you this card appreciates that you were respectful and modest instead of provocative and indecent. It might not seem like much, but you could have received a red or yellow card instead. Cheers!
Yellow card: SLUT MOVE!
If you have received this card, you have dressed or behaved mildly inappropriately in front of the person who handed this to you. Your intentions might have been good, but before going out in public again make sure that you are dressed and behave respectfully and modestly.
Red card: SLUT MOVE!
If you have received this card, you have dressed or behaved wildly inappropriately or otherwise sexually provoked the person who handed this to you. You should be happy you got a card and were not raped. Check yourself - you might not be this lucky twice!
