A Dust bunny is the female methamphetamine connoisseur. Usually in furry slippers, booty shorts, with a shirt that stops just short of covering her bloated and distended abdomen. She usually will carry a bag of some sort hanging precariously loose from her persons. She has an innate ability to find, procure, and consume amphetamines.
Dust comes from a colloquial term for methamphetamine while the bunny part of the adjective is derived from the term "snow bunny".
