When a group of bro's begin to fist pump so hard that a whirl wind begins to form and then from that, a Bro-nado rips through the party.
Me and all the bro's on my team were fist pumping so hard that we had a B-4 Bronado rip through the whole party. No quit.

When one is having a party of sorts and super bro-y, bros crash said party and decimate the place in which said party was being held.
It looks like a tornado just hit the bitch...No dood, it was a muthafuckin' Bronado.

(n): an individual, of male gender, comprised of an exemplary amount of bro-ness and tornadoes. When conjoined, these two factors give the recipient powers capable of altering the space-time continuum to appear everywhere at once, yet nowhere.

When entering the nature of broanativity, the bronado becomes immaterial, impervious to any form of restraint short of a black hole.
Yo, Tony, did you see Justin? He just went Bronative on us. Unstoppable!

Us Bronadoes gotta stick together, who knows what's out there.

The occurrence of a tornado in Brooklyn, witnessed and recorded on camera by two males (preferably brothers) who will exchange expletives to each other and the utter destruction of surrounding forestry as they stand there and look at it from their balcony.

A high-risk or high-frequency bronado zone. Possible high-risk areas include: sports bars, sporting events, establishments with free or bottomless drinks, party busses, fraternity houses, bachelor parties, buffets, VIP areas with bottle service, and pretty much anywhere bro-iness and substance use create ideal bronado conditions. It should be noted that being located inside any of the aforementioned areas means you are deep into the danger zone and should take emergency measures. If possible, seek a nearby bronado shelter.

It's generally a bad idea to pass through that bronado alley — especially after the bars close. I must've seen at least 5 bronados the last time I ventured into that bar.

Designated bronado-free safe havens. Examples of effective bronado shelters: libraries, farmers markets, museums, art installations, hipster-occupied coffee shops

Unlike tornado shelters, there's no universal wayfinding signage to guide you to safety, so emergency preparedness and education are key to ensuring your safety. Bronados form when a group of amped bros form together. Be on the lookout for visible warning signs, including but not limited to: drunken high fiving, fist pumping, backward caps, v-neck or popped collar shirts, excessive hair product and/or cologne. Audible clues include loud use of the words bro, champ and boss.
Good thing we saw that bronado shelter, otherwise we could've been subjected to high fives and found ourselves at a party with beer pong.
