A Bro-ner is when you get an involuntary erection from doing something testosterone fueled and hella not gay with the bros. Popping a Bro-ner around bros is quite acceptable, and they will probably call you a "stud" and ask if you want to hit the gym or chug a fifth of Jaeger.
"Me and the bros were watching 300/ latest UFC fight last night and it was so sick, I totally got a Bro-ner."

"Dude, Mike put up 250 on the bench last night. I so got a Bro-ner"

"Poppin' collars, poppin' Bro-ners"
