Cards Against Humanity is an adult card-based party game in which players complete fill-in-the-blank statements, using words or phrases typically deemed offensive, risqué, or politically incorrect, printed on playing cards. It has been compared to the card game Apples to Apples (1999).
The game originated with a Kickstarter campaign in 2011. The game's title refers to the phrase "crimes against humanity", reflecting its politically incorrect content.
