look up any word, like thot:
 
1.
the zombie day of reckoning
"Holy shit, it's the zombocalypse!"

Literally the word zombie and apocalypse put together... as best illustrated in the 28 days later movies, and dawn of the dead.
Did you see dawn of the dead where that one guy was wearing a tie during the zombocalypse... what a douchebag

The state of the planet in which society has crumbled and the looming chaos and lack of rule has paved the way for a zombie invasion of epic proportions.
Now that the government has dissolved and no one knows up from down in our "society," a zombocalypse is inevitable.
