A very ugly girl who sits in the backseat of the car when she is out with friends because she is too ugly to sit in the front seat where she would be seen much easier by people outside the vehicle
Hey Jenny! Come sit in the front seat before Barb gets here because I don't want that backseat bitch cramping my style.

A backseat bitch is when you got niggas walking around with thier dudes,and they agree with everything they say.
