Monolid or mono eyelid or Mongolian
fold (outdated incorrect term) or Epicanthic fold (technical term) or slanty eye (derogatory term) is a single eyelid, instead of double eyelids. Monolid is not solely an Asian trait. Those who call it Asian eyes are too
dumb and ignorant, usually Americans because they
don't live in Europe, to know that many Europeans and Africans have this trait too. European ethnic groups that tend to have epicanthus relatively frequently are Scandinavians, Poles, Germans, the Irish and
British.
Student: "why do Europeans have Asian eyes?"
Master: "because they'
re not Asian eyes. Europeans have it too. They'
re monolids, you cunt eyes."
