no-pocalypse 

This occurs when Judgment Day, as predicted by a fool and his followers, passes without incident.

I wish I could go to your no-pocalypse party but since the Rapture didn't happen, I need to do my homework. Bummer!

napocalypse 

When you mean to have a quick nap, but instead sleep for hours and throw off your schedule.

"What happened to you? You missed the show last night."
"The Napocalypse hit."
"Ah, ok."
