When one or more bros gather and collectively deem themselves as "amazing" just by being together. (ie: Bros being together automatically makes them amazing)
Originated with Australian prison inmates who would resist transfers/court appearances by smearing themselves with their own faeces - derived from the analogy of applying 'bronzing' sun tan lotion.
"They smeared themselves with their own waste, but the protest (known in jails as bronzing up) proved futile when they were later told they were not required at court." News.com.au, September 17, 2004.
A Fund which consists of the pooled assets of several bros. A Brommingled Fund invests most of its assets in developing markets (i.e. Bromania, The Chick Republic, and Buttswana).
Tanner: Dude, our Brommingled Fund is down circa 10% this month!
Chad: Bro, you can't panic every time there is a correction in the Gangbangladesh market!
The stuff in a man's DNA that allows him to share information surreptitiously with other males.
EXAMPLE 1:
Guy 1 to Guy 2: That was a nice space to get out in.
(intrinsically implying that in the past few moments a guy could have scratched, worked out, or rested his eyes)
Guy 2 to Guy 1; Yep.
(he's pretty much indifferent when it comes to all that stuff but agrees it could have all happened.)
Girl in the Back Seat: Are you guys talking about sex? I don't have BROMATIN like you.
EXAMPLE 2:
A lady is easily fooled into thinking a man is simple to understand, but a female can't help but be misguided due the the presence of BROMATIN on his Y chromosome.
