Papyrus Irony refers to a subgenre of Undertale-themed shitposts that transform the upbeat, spaghetti-loving skeleton into a vehicle for surreal, absurdist, or 'ironic' humor. Unlike the wholesome canon depiction, these memes often feature Papyrus expressing existential dread, niche internet opinions, or nonsensical rants, often presented with low-quality filters or exaggerated Impact font. The trend emerged as part of the broader 'Irony' movement on platforms like Discord and Reddit, where fans subverted the earnest nature of the original Undertale fandom. Today, it remains a staple for creators who want to blend nostalgia with modern internet brain-rot, making it a favorite for those who appreciate the bizarre side of gaming culture.
