Much more comprehensive than just a gunt. A Guntunda is when the gunt is not restricted to simply the front of the body, but instead wraps around the entire back and meets on the other side. Side, front AND back, the whole package of fat. It takes a special sized and shaped woman to display this, along with the proper clothing choices. A delight for gunt lovers everywhere.
Sha'niqua was so far beyond obese that her gunt turned into a guntunda.
When a woman possessing a wordgunt/word wears pants much too tight for her prominent girth, thus producing a wedgie effect which drives witnesses to gouge out their eyes with the nearest rusty garden implement. Credit belongs to Canadian G. Mellum for coining the term in 2001.
Mrs. Chastko had such a guntgie that I wished to drive a serrated trowel into my left eyesocket.
