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!
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.
When one or more bros gather and collectively deem themselves as "amazing" just by being together. (ie: Bros being together automatically makes them amazing)
