Fossa  

Despite the previous definition, (which also happens to be spelled incorrectly - ie: Foosa), this animal does indeed exist. It is NOT however a slang term used to refer to hyenas, as previously stated. Many people have recently been introduced to this animal by the movie "Madagascar." The Fossa(Cryptoprocta ferox)is the largest carnivore endemic to the island of Madagascar, and is a catlike member of the civet family. It usually hunts alone and commonly feeds on birds and lemurs but also preys on livestock. This is precisely why the lemur characters in the movie were always afriad of "The Fossa!"

For an expanded definition and pictures of the Fossa please see Encyclopedia Brittanica online.

"We thank you with enormous gratitude for chasing away the fossa (foo-sah).

fossa 

something that is built up to be great but is utterly disappointing. The Fossa is a meat-eating mammal from the island of Madagascar and was built up at Marwell Zoo to be the most 'mysterious creature' about. It was rubbish.

Fossa Behavior

Behavior that reflects that of the fossa, top-chain predators in the jungles of Madagascar, and are infamously known as the disruptors of King Julien's parties in Madagascar. Fossas are known to be short-tempered and often make bad decisions for their own self-benefit without considering others in the pack. They are extremely aggressive when it comes to mating, and will pursue the mates of their packmates with no respect for themselves or others, often engaging in passive-aggressive competition.

King Julien: Watch out Mort, even though we may be away from Madagascar there are many people who exhibit Fossa Behavior
Mort: Oh noooo....KING JULIEN, LOOK! There's one that keeps calling the den, and another who keeps visiting the den to try to mate. What are they competing for???
King Julien: Fossa behavior Mort. Fossa behavior. Stay. Away.
