1. A chick that is decently looking/attractive in the face, but also has qualities of a nice rack (mostly the rack) and butt that come from her being overweight/fat. Unfortunately she is overweight so she will have a spare tire around her waist as well as thighs that are almost as big as 155mm howitzer shells.

2. Can also be a good looking chick with the same qualities ( rack and butt ) as the above and might not necessarily be overweight, but can be heavyset, or voluptuous.

The hourglass and pear female body shapes are typical examples of the the second definition.
