brofirmation 

The act of asking your bro to confirm a girl's attractiveness before taking her home (more commonly done when you are more drunk than your bro)

I had like 12 beers and was about to bring this girl back to my apartment but I needed a brofirmation from Sam before I could take her home. He gave me the brofirmation so we left the bar and went to my place.
