2 or more bros who are easily interchangeable between one another. If one Brotondo is busy, the other one(s) can easily fill his place.
Brotondos usually supply the bros with many brotivities, as well as a place to hang out / drink brewskis.
Also, Brotondos will never break the standard Brotocol written in the bro code. The bros usually have a preference when it comes to choosing which Brotondo to hang out with.
The sublime and highly sought after status of being so bro that everyone idolizes you. This includes wearing V-necks, fist pumping, and getting girls.
One must never put a ho before a bro or will face suspension and/or possible expulsion from Brotorious.
Bros must drink excessive amounts and dance on any object possible (coffee tables, stoves, refrigerators, etc.)
To gain official Brotorious status one must go through "Bro-nitiation" which involves partying for a weekend with some Brotorious Bros in the "Bro-Dome" who will put you to the test and vote on if you have what it takes.
Girl: "OMG did you see how fucking sexy those bros were."
Guy: "Yeah there so rad they have to be in Brotorious"
Bros: (in the background) "Bro-Bro-Bro-Brotorious!"
Brotonial is a weird person that has an unnatural obsession with cheese, snapchat and singing obnoxiously loud in the shower. He is not a ladies man and ladies stay away, he's probably got a boyfriend.
