A meme in which a character eats a Lemon, audibly munches it for a few seconds, and finally "dies" with a distorted scream and appearance.
The meme originated from a video titled sonic eats a lemon and dies made using Discord emojis. This version simply had Sonic grunt at the end. A later parody with Hatsune Miku titled miku eats a lemon and dies added a longer and more audible munching as well as the distorted scream at the end. This version became the more well known version of the meme.
