M.O.T. is shorthand for Map of Tasmania, and slang for the natural female pubic area. Tasmania is an island state, part of the Commonwealth of Australia. When viewed on a map, the island resembles the natural triangle shape that appears when women do not shave or otherwise excessively alter their pubic hair.

The artist Amanda Palmer popularized the term in her hit song “Map of Tasmania.” The lyrics include the following popular verses:

Walking down the street, I’m the lady showing off my map of Tasmania.

Soft and sweet and shaped like a triangle
Some girls want no shape and they shave it all
That's so whacky, hurts with the stubble
Walking round, look like an eight year old

I say grow that shit like a jungle
Give 'em something strong to hold onto
Let it fly in the open wind
If it get too bushy you can trim
