Term referring to the film Manos: The Hands of Fate, a film generally regarded as one of the worst ever made. The phrase is used in regards to something really unfortunate happening to a person.
Dude, that chick you just made out with is a man. You just got Manosed.
I'm sorry your car was vandalized in the church parking lot. Just goes to show you can never tell when you're going to get Manosed.
A pear-shaped homosexualmale, characterized by a large round buttocks and bulbous belly, below a thin upper body. Movement of a mangoose can best be described as waddling, while thin birdlike arms are held horizontally with hands dangling limply at the ends (similar to the arms of a Tyrannosaurus Rex).
I'd fuck a fat lady before I'd touch Puddingbutt, he's a total mangoose.
