In one classic case, the Kelly-Hopkinsville sighting in 1955, two rural Kentucky men described a supposed encounter with metallic-silver, somewhat humanoid-looking aliens no more than 4 feet (1.2 m) in height.

Today, these creatures are more commonly associated with an alleged alien species called greys, whose skin color is described as not green, but grey.ĭuring the reports of flying saucers in the 1950s, the term "little green men" came into popular usage in reference to aliens. The term is also sometimes used to describe gremlins, mythical creatures known for causing problems in airplanes and mechanical devices.

Little green men is the stereotypical portrayal of extraterrestrials as little humanoid creatures with green skin and sometimes with antennae on their heads.
