Definition of «y/n»

"Y/N" is a fandom placeholder meaning “your name,” inserted into second-person self-insert fiction so readers can imagine themselves as the protagonist. It is especially associated with reader-insert fanfiction, screenshots, memes, and jokes about stories that treat the placeholder as a fully developed character. The form is usually written with a slash and capital letters, although casual posts often use lowercase. Because it represents the reader rather than a fixed individual, people may mockingly call Y/N a character when a story gives the placeholder an independent personality.
