land manatee 

A very large dispicable human being with bright blue eyes and no neck RR. Bearing a striking resemblance to a wild manatee, she tends to have a large ass where the bulk of the blubber is stored. Her land waddle has been known to severly injure small children, and crack the city streets that she prowls on.

Yeah dawg, can't believe you hit and quit that land manatee.

A nice little animal thing that swims around and is cool and gentle and harmless, but gets fucked up by boats going to fast.

Manatee joke 

A manatee joke is a kind of humour popularised by Family Guy and satirised by South Park. A manatee joke is when one of the characters says something that has nothing to do with the plot or characters in the show, but leads into a flashback of the scene described

"Remember that time you slept with Bill Clinton?"
(Cuts to a scene of Lois boinking Bill).
"Oh Peter, remember when this show used to not rely on manatee jokes?

Land Manatee 

An incredibly fat person. In particular, a Land Manatee has little in the way of recognizable skeletal structure. Rolls of fat disguish the neck, as well as much of the arms and legs.

Unlike the real Manatee which arguably faces the threat of extinction, the Land Manatee enjoys ever growing numbers thanks to North America's penchant for fatty food and over eating. The Land Manatee faces no natural predators and lives primarily off fast food and frozen TV dinners, though they are also known to eat vast quantities of pretty much everything.

Burger King Employee: "Our deeper fryer is empty! I mean the grease is completely gone, sucked dry."

Manager: "Land Manatees....Get the harpoon gun, they can't have gone far."
