Similar to a FUPA or Gunt, in that a large sack of fat is present in the upper genital area, however a Bumper Cunt is present only when the FUPA is shaped more like a car bumper in that it is exceptionally short from top to bottom, but very wide from buttocks to pubic area. An extereme FUPA. Similar in shape to a skin draped shelf.
Yo! That bitch ain't got no regular FUPA, shes got a fuckin' bumper cunt!

She knocked over the vase with her huge bumper cunt
