choppelgänger
/ˈtʃɒp.əlˌɡæŋ.ər/ (CHOP-uhl-gang-er)
noun
A grotesque or markedly uglier counterpart to a
doppelgänger; a person who looks eerily like someone else but in a hacked-up, disfigured, or visually degraded way — as if the original had been “chopped” by a bad haircut, poor lighting, plastic surgery gone wrong, or a lifetime of
questionable decisions.
Etymology
Blend of chopped (slang for mangled, butchered, or ruined) +
doppelgänger (German, “double-walker”). First coined as a humorous portmanteau to describe the unsettling experience of meeting your evil, less-photogenic twin.
