It's been far too long.
Yes, following more than a year's hiatus, I am once again cracking open the pages of Brocabulary: The New Man-i-festo of Dude Talk to explore it's hallowed teachings.
The topic this time around is a simple yet vital one: some different kinds of bros, as covered in the chapter Brommunication (n.) The art of communicating in a brophisticated manner, with or about your bros
sack pack - A bunch of dudes traveling in a group, or a cock flock. When they turn into a door jam by jockeying to get into a club, they're known as a bluster cluster, and when they storm a party they're known as a bro storm.
cerebro - The bro who does the thinking for you. You're R2-D-Dude and he's C-3P-Bro.
guyamese twins - Two bros who are pretty much inseparable (eg. Batman and Robin, Matt Damon and Ben Affleck, Michael Knight and KITT)
PAL 2000 - when a bro who seems to have your best interest at heart suddenly turns on you like HAL 2000 in 2001: A Space Odyssey, usually by giving you bad advice and claiming it's for your own good: "The dude was my brother half until he PAL 2000ed me by convincing me to dump my girl and then hooking up with her. He totally soaked me in traitorade."
wannabro - A dork who tries to be a bro but is nothing but a wannabe. Sometimes referred to as a wannaDB as in "Dude, you're not even a douchebag, you're a wannaDB."
Vincent Van Bro - A bro who is so loyal he would cut his ear off for you.
