Slut Dropocalypse 

The name given to a theory of how mankind will end.

Intoxicated, promiscuous females often suggest sexual attraction by doing a "slut drop". When the Slut Dropocalypse occurs, an overly drunk female will slut drop in heels too high and will struggle to get back up. Nearby people will either be too drunk to help or will find it too funny to help. The girl in question will die from either starvation or embarrassment, and this will create a wave of inevitable slut drops until all of woman-kind die out. Without females, not only would humans no longer be able to reproduce, but there would be no woman to cook the men's food, and hence the end of mankind.

It is said Slut Dropocalypse will begin in 2058 when promiscuous dancing is at an all time high.

I just don't understand why Stacey Slut Drops like that, is she speaking to the devil trying to trigger the Slut Dropocalypse or something?!

demopocalypse 

An IT term for a demo of a computer program given to stakeholders or important clients before the program is actually done. The demo is sure to fail and certainly cost your project buy-in and/or it's reputation. A demopocalypse is most often brought on by asshat managers or sales people who didn't even bother to ask for the current state of the project before promising a demo.

Question: Are you still working on that new sales logic system for client x?

Answer: No. Our CIO promised a demopocalypse to the stakeholders and they pulled the plug on our funding. Mind proofing my resume?
