This is what you give a guy in a bar when he's annoying you and asking for your number over and over again. It reads: You are a douche. Maybe he'll get the hint then.

We've all been in this situation: in a bar, at a meeting, in line at the cash register, on the elevator, on a date, and someone is being an idiot. Now you can let them know.

Give them the douche card. Much like a yellow or red card, it conveys its message succinctly, although in this case you might want to run after handing it out.

why didn't they have this when i was a teacher's asst???? that would have been hilarious.

Let's say you're standing in line inside subway. Someone kindly cuts in front of you to stand next to their friend in line. Tap them on the shoulder and hand them this. I think the point will be clear.

One of the many instances this card would come in handy.

these are perfect for the hit and run insult! just a little "you're a punk" reminder card!

These are so useful. I can hand them to people on the street, at the grocery store, at the movie theater, anywhere! And they need to know that their behavior affects others.

I want these so much. It would make many aspects of my life easier.

Next time someone cuts in front of you in line, hand him one of these. I got one from a friend (no really, just for fun) and it's pretty funny. It's on glossy thick card stock and very minimalist so at first glance you think it's some classy business card.
