A word originally used to describe self-manipulation. It evolved into a description of what one intends to do with the course of the day, ie, to replace the common slang term 'nm'. It then completely degenerated into a word that, once said, would be repeated by every person within a twenty foot radius, reminiscent of the seagulls from Finding Nemo.
Person 1: Hey, why didn't you call me last night?
Person 2: Sorry, Jeff Goldblum was on A&E, and I had to MABATE!
Every person within a twenty foot radius: MABATE!
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.
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?
