The truest form of the mullet, it contains 10 percent of hair on top and 90 percent in the back.
Did you see that guy driving the Camaro.
No, why?
He had a sweet 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....
