3DPD, an acronym for '3D Pig Disgusting,' originated within the otaku and anime subcultures of imageboards like 4chan’s /a/ (Anime & Manga) board in the late 2000s. It is used by fans to express a humorous, exaggerated preference for 2D fictional characters—specifically anime girls—over real-life 3D women. The phrase often accompanies images of anime characters looking revolted or pointing at 'real world' elements. Over time, it transitioned from a niche insider term to a widely recognized meme within the global anime community, serving as a satirical battle cry for those jokingly rejecting reality in favor of their favorite waifus.
