Grecoman, (plural: Grecomani or Grecomans; also known as Graecoman, plural: Graecomani or Graecomans), literally meaning "fanatic Greeks", or "fanatical Greeks", (Greek: Γραικομάνοι, Grekománoi, Bulgarian: Гъркомани, Garkomani, Macedonian: Гркомани, Grkomani, Romanian: Grecomani, Albanian: Grekomanë, Aromanian: Gricumanji) is a pejorative term used in Bulgaria, North Macedonia, Romania, Albania, and Italy to characterize Albanian–, Aromanian–, and Slavic–speaking people, who self-identify as ethnic Greeks. The term generally means "pretending to be a Greek" and implies a non-Greek origin.
The term is considered highly offensive to Greeks. The "Grecomans" are regarded as ethnic Greeks in Greece, but as members of originally non-Greek, but subsequently Hellenized minorities, in the neighboring countries.
