The meme originated from a video of YandereDev drinking milk out of a glass chalice. There was a GIF created in early 2020 of YandereDev drinking out of the chalice with the captions 'CONSUME THE CUM CHALICE' inferring that the chalice was filled with semen rather than milk. It has gained a large amount of popularity and often used to criticise YandereDev online, and is now a method of getting banned from his Discord server. The GIF has inspired a whole new generation of memes and is now widespread among memers.
