Have you ever played Cards Against Humanity? If not, go and buy a set, gets some beers in and invite some friends round. Most o the time you will be laughing so hard you will be praying for stronger bladder control. The rest of the time, you will be giggling because it'd just filth.
I've just seen a promo for Cads Against Matrimony. I don't normally push kickstarter but suggest that this page might be worth a look. There is so much I like, I can't risk looking at it.
