10-90

The perfect way to describe a mullet thats mostly mullet and almost no bangs. Can be used openly in public, because no one knows what a 10-90 is.

10% bangs, 90% mullet; 10-90

Person 1: HOLY SHIT!!!! Do you see that 10-90?!?!

Person 2: Hell yeah!! There's VERY little business in the front, and one hell of a party in the back....
