The Xbox 360 live headset. Commonly used amongst teenage boys (the bros) playing call of duty or other intense games so that they can communicate with fellow bros about their excellence in life.
While playing call of duty, Steve hooked up his brophone so that he could effectively communicate with Adam and tell him how many kills he was racking up.
I threw my socks in the hamper and they wound up under my underwear and I wondered if they were judging me for that...then I realized I was just Broshing.
