Ratchet

A diva, mostly from urban cities and ghettos, that has reason to believe she is every mans eye candy. Unfortunately, she’s wrong.

Typical signs to beware of include, but are not limited to:
-owning a Blackberry
-BLARES anything by Drake, 2Chainz, Nicki Minaj, Gucci Mane, Waka Flocka, Lil Wayne, T-Pain, Cali Swag District, or any other garbage entertainment rapper
-rowdily quotes “lyrics” from aforementioned artists
-has a weave reminiscent of a bird’s nest after a tempest hit the tree it was in, and is dyed at least thrice
-wears torn leggings/stalkings (mostly of the fishnet variety), unpolished 8″ heels (or higher, depending on how God-awful they look), fitted jean jackets (to accent the blubber ’round their arms and stomach), and 4 layers of caked on make-up to go clubbing
-repeatedly use ludicrous terms such as “YOLO”, “swag”, “boost”, “beaking”, “doe”, “really”, “naw”, “actually”, “twerk”, “coaster”, “dagga”, etc., to make a valid statement when they speak
-have side bangs, despite having incredibly small-ass foreheads to support them
-are commonly overweight
and are mind-numbingly stupid; a safe assumption to make would be saying they’re uneducated (as if they could pass the 4th grade)

If spotted, please report to the authorities, notifying them that they are possible smack addicts, or potential, degenerate Chaka Khan look-alikes.
