My current favorite game is Cards Against Humanity. In fact I got the first and second expansion packs in the mail today. They open like this. [18+] It's an open source card game, so you can buy it or print out your own set via free PDFs. It's like Apples to Apples, but with the sort of sick and twisted shit Fazers would enjoy. Best played with friends that don't require needing the terms bukkake and tentacle porn explained to them.
Also it's currently sold out in the US, but you can sign up to be notified when it comes back on the site. @CAH is currently estimating Monday, when it's sure to sell out within a week again. CURRENTLY BACK IN STOCK SO GO GET IT!
