(n.) A woman of questionable purity whose popularity with the opposite sex is due entirely to the most highly-developed aspect of her anatomy - her breasts. A "boob skank" is so ugly, though, that were it not for the attention due to her breasts she would never get a second look from anyone.
It's a good thing that Stacy has 40DD's so that nobody has to look at her face! She is such a boob skank!
