A chud is a slang term used primarily in online discourse as a pejorative label. In modern usage, it typically refers to individuals perceived as reactionary, uninformed, or excessively aggressive in political or cultural debates on the internet. The term is often employed to mock or dismiss certain viewpoints rather than to describe a clearly defined group or ideology.

The word originates from the 1984 cult film C.H.U.D. (Cannibalistic Humanoid Underground Dwellers), though its contemporary meaning is largely unrelated to the movie. Over time, “chud” has become a common insult in online communities, particularly on social media platforms, forums, and image boards.
