The J is slang for "UNDERSWAP PAPYRUS" and "PAPYRUS UNDERSWAP". First time it was used was when a au called "comedytale" wrote the letter "J" on papyrus' jacket from the hit indie game, UNDERSWAP. After it has become a large meme in current internet culture and now stands with us today as nostalgia from the past for underswap.
