The act of giving your bro a massage after a tense day at work or the gym. Two dudes rubbing each other just to help out.
Camman: Yo Bridawg your shoulders look all tense today why don't you hop off that forklift and let me give you a brosage.
Bridawg: Dude, I thought you'd never ask. Brosage me up.
