Broner is not a object like a boner. Broner is a fealing of happiness when with one or more of your "bros". broner can be used as a gay term but will not hold the same meaning. Non gay word. If another guy comments on a mans broner it is now gay.
Non-gay<normal meaning> Dude that was a good run it gave me a broner. Gay<dont use it> Dude your'e broner is so big, dude look at my broner, my broner is so big.

A Bro, or dude, who gets an erection when no girls are present.
John: "What the fuck Steve, you have a broner right now!" Steve: "Oh...no thats just my pants...." John: "Whatever man your a fucking homo."

When a male randomly gets an erection while in the presence of his male friends. There is nothing sexual about it.
Guy one: Dude, why do you have a hard on, when I'm the only one around? Guy two: It's a broner dude, don't worry.
By I say, now.
