1) Bug Eyed Monster. A stereotypical being from another planet, usually depicted with buglike eyes.
2) The truncated name of a Japanese anime TV series, "Yokai Ningen Bem", and the name of a character from that series, in Japanese: Bemu. The series featured alien crimefighters, at first distrustful of humans but later learning to deal with human platitudes.
1)Help! There's a BEM trying to attack me!!!!
2)I'd like to know where I could get a translated video of BEM.

an old sci-fi abbreviation for 'bug-eyed monster'. Dates back to the time of movies of the week that were so stereotypical, people made abbreviations for each kind of character.
Also an episode of Star Trek: The Animated Series, and the preffered name of bemdude
God, that BEM is fuggn' weird.
