Social media users have been left stunned after discovering that there are not one, but two, hidden cards in the Cards Against Humanity box.
For those unaware, the card game is a self-described "party game for horrible people" where you get a prompt card and have to match your answer to make the most humorous (and inappropriate) possible scenario.
However, what many didn't know is that there are actually secret cards hidden within the lining of the box itself.
Charlotte Emily Gree - who goes by the handle @charlotteemilygre on TikTok - took to the platform to share her disbelief at the secret card in a video, with overlay text reading: "When someone told us there was a hidden card and we didn't believe it."
Check out Charlotte's TikTok below:The clip showed someone slicing open the bottom of the box with a sharp knife to see if the rumors were true - only to uncover a new white response card.
The person cutting the box open was stunned as they came across the first card which read: "The biggest, blackest d***," prompting chuckles in the room.
"Wow, that's a good idea!" someone in the video could be heard saying - possibly referencing how the hidden card is only found inside the game's Bigger Blacker Box, rather than the standard version of the game.
As of the time of writing, the video has amassed 84.1K likes and 981.8K views on the social media platform, with many people sharing their reactions to the unexpected finding.
One user wrote: "I need to check mine now, don't really want to ruin the box though. I'll get back to you all."

Another user questioned: "Why would they hide a card like that?"

A third person commented: "Are they also in the small box? I don't wanna ruin it to find nothing."

Lastly, a fourth user remarked: "This is amazing marketing actually, because people are now gonna buy it just to see if it's actually true."

In addition to this, people were also quick to reveal that there's actually a second hidden card too, with one user writing: "There’s apparently one in the other half of the box as well," to which the astounded TikToker responded: "This better be true!!"

Another user also pointed out: "Yeah there's one in the lid and one in the middle bottom part," while a third wrote: "There's two hidden cards actually, there's another one inside the tray."


Charlotte soon had the boxcutter out to check out the other card - which did indeed exist - as she and a friend ripped open the lining of the bottom half of the box.
The pair were similarly stunned to find the second hidden card read: "A d*** so big and so black that it is a problematic stereotype."
While it seems like we've all been floored by this discovery, the users in the comment section that knew about this secret said that the only game that has the famous hidden cards is the Bigger Blacker Box.
So please, don't go tearing up any other edition of the Cards Against Humanity box that you have at home!
