Bropocolypse 

When an entire community of Bros' have died in a very short period of time.

Jim: Dude, did you heard about that bropocolypse that happened last week?

Sam: Yeah man, it was a brotastrophy!

Bropocalypse 

A large gathering of bros on a mission to do one thing, to get bombed, tanked, or wasted usually ending in some people doing something stupid.

Bropacalypse 

The impending end-of-days that will be brought upon the world by the rising culture of douche bags otherwise known as "Bros". While the prophecy is unclear it is certain the Jeep's with massive lift kit's blasting songs by disturbed and tool will rain down from the skies, every being on Earth will be adorned with pink polo shirts untucked with the collar popped and extended several feet, and a terrible cacophony of the words "bro" and "broseph" will emanate from no certain place but will be heard everywhere.

I feel that MTV's television show "Bromance" is the first of four signs of the impending Bropacalypse.

Bropocalypse 

When the boys all get together with one goal in mind. To roast as many savage bints as possible. Preferably ones without felted mounds and absolutely no gashes.

"Yo Bro!"
"Ya."
"Sup tonight?"
"Looking to set up a Bropocalypse, you in?"
"Ya, for sho. Lets wheel some slappers tonight!"
"Im down for that. Hopefully they have dripping deltas, so I can slide into their crawl spaces!"
