The insult “chud” comes from a 1984 horror film called C.H.U.D., which is an acronym for “cannibalistic humanoid underground dwellers,” which are the monsters in the movie. Colloquially, this term is used to call someone stupid, ugly, or troll-like, as the monsters in the movie are. Online, the term is often used by leftists to insult conservatives, sometimes with qualifiers like “MAGA chud” or “#BlueLivesMatter chud.”
