In 2008, webcomic Ctrl+Alt+Del published a strip where the protagonist's girlfriend miscarried. The internet hated it so much that the strip eventually got reduced to four lines and a corner: | || || |_. That shape went on to seed an entire genre of pattern-recognition memes, and seventeen years later, people are still finding it hidden in Among Us crewmates, Geometry Dash levels, and FlightReacts screenshots.
