Clusterfuck is a card game you can play at parties. It's about sleeping with everyone around you. Easiest way to score an instant win? Have a threesome (in the game).
It's part of Cards Against Humanity's '12 Days of Holiday Bullshit.' Best of all? It's free.
Created by Zach Gage, Doug Wilson, and the Cards Against Humanity team, Clusterfuck looks like a fun way to spend some time with friends during the holidays. Although you probably shouldn't bring it to family dinner. If you didn't sign up for the Holiday Bullshit, you can download the game for free here.
