M.N.P.

stands for must not procreate.

Applied to morons who, by law, should not be allowed to make children.

Bill: so, last week, I started para sailing and I was looking up at the sky instead of the ground, so I look down and see that I'm about to land in this swamp full of alligators.

Me: wait, you para sailed over a fucking swamp?

Bill: yeah.

Me: dude you are beyond M.N.P. You're to the point now that you're too stupid to exist.
