When you have cocaine remnants left in your nose following a three day binge. Often resembling a booger but white.
"Aye bruh, ole boy that came over here you knew he was on that white girl. He had all kind of albino bats in his nose."
"Co-worker. - You have alot of those albino bats. You might want to go clean your nose.
Me. - Note to self. Clean nose after coke."
