What Do You Meme -- an adult-aged card game courtesy of a three-year-old startup of the same name -- is linking up with the infinitely meme-able YouTuber Bretman Rock on a limited edition product launch. Rock, a beauty guru with 6.8 million YouTube subscribers and 13.8 million Instagram followers, has released an expansion pack of cards to complement the core What Do You Meme game. The popular title sees players competing to become crowned the Meme Queen or King by matching photo cards and caption cards in order to concoct funny meme combinations. The company has already released a number of expansion packs with different themes and partner brands like 'For The Girls', '4-Bidden Words', and The New Yorker. Bretman’s limited edition pack went on sale yesterday ans is priced at $15. It comprises 15 cards bedecked with his photo, as well as 50 caption cards. Given that the core What Do You Meme game is required in order to play with Rock's expansion pack, the company is offering 20% off the flagship title if consumers enter code 'Bretman20' at Amazon checkout.
