flock + apocalypse = Flockpocalypse
When a large number of birds dye and fall in the ground for no apparent reason.
Odd event which took place during the first days of year 2011 in Arkansaw, Louisiana, Kentucky, USA and other large amount in Sweeden.
Dude 1: Have you seen the news about the flockpocalypse on the TV?
Dude 2: Yeah man! That shit is weird! I wonder if the end of the world is coming soon. Animals always know first!
