Little Green Space Men

Little Green Man used to be the blanket term for aliens, we don't use this term much anymore as most people as it has been surpassed by the modern Greys, in the past there wasn't a John, Jessica or Jeremy who didn't think that someday they'd have to fight a Little Green Man in a flying saucer and kick his ass all the way back to Mars!

In Real Life
The story of the term Little Green Man begins in the town of Hopkinsville, Kentucky, on the evening of August 21st 1955 a family was attacked by strange, otherworldly beings, The Hopkinsville Goblins!, they reported the creatures to the police and the pigs then proceeded to get some armed forces to fight these beings, but just as quick as the goblins where there, they where gone and all that was left was the farm, riddled with bullet holes.

Following this event, the news papers called these beings "Little Green Men" and the term stuck, and that is one of many times pop culture has been influenced by real cases of otherworldly encounters.
