The Cum Chalice meme refers to a viral video about Yandere Simulator developer YandereDev toasting with a glass chalice filled with milk and drinking from it. In January and February of 2020, a meme GIF based on the video which was captioned "Consume the Cum Chalice" (implying the chalice was filled with semen instead of milk) gained popularity, largely in connection to YandereDev being criticized online and as a means of getting banned from his Discord server.
