Ranking of females whore factor. Like the Gonzo Fuck Scale as referenced on Playboy Radio which ranks limits of sexual acts (D-P, etc), the Duey Scale ranks how many guys the female will perform these acts with and length between these acts.
Pornstar Houston is a perfect 10 on the Duey Scale after fucking 620 dudes in one day!!

Goodness that slut looks like she'd be a 10 on the Duey Scale... she's talked to every guy in the club!

The Dirty Duey is when you fuck a chick missionary but your right eye turns inwards and you ejaculate while looking at the dog instead.
I thought he was looking at me but he did the Dirty Duey.

A Duey is a badass. A Duey will often only start fights if he is outnumbered.
