The 'Let Me In Please' meme features TikTok sensation Charli D'Amelio pressing her face against a glass door, appearing to beg for entry. The image is a screencap from a video where Charli was jokingly trying to get back into a house. Since its emergence, the template has become the universal symbol for FOMO (Fear Of Missing Out) and exclusion. Internet users frequently pair it with captions about being left out of group chats, watching others enjoy a new video game, or being barred from exclusive social circles. Its popularity stems from Charli's massive following and the highly relatable expression of desperation mixed with humor.
