As a bro makes he's line-up of clothing for the night, he makes an attempt to not show off with nice clothing but at the same time tries to appear better than everyone else. The combination is casual + bro = brosual. a t-shirt, jeans, gelled-hair and an excentuated body makes a casual night that much more bro
