shortstack

A character who is short and thick in stature, but with curvy and exaggeratedly well-endowed types of proportions.

Shortstacks that are more feminine are both top-heavy and bottom-heavy curvy figures on a short and thick type of frame.

Shortstacks that are more masculine tend to have short, squat, male-bodied with generally bottom-heavy and/or curvy figures.

Overall, shortstacks are a combination of wide_hips, thick_thighs, big_butt, (and big_breasts if feminine-bodied); sometimes they can be chubby, voluptuous or overweight. They may also feature hyper proportions in either breasts or hips and thighs, or genitalia, or both. The original term for this body type comes from the combination of short (referring to the character's height) and "stacked" (slang to refer to someone having large breasts or curvaceous body).

Criteria

A "shortstack" character should have/be:

Of short height

Tagging notes

While often shortstacks characters have either a curvy_figure or a pear-shaped_figure, if they don't have "short stack" proportions, they should not be tagged as "shortstack".
Not all voluptuous female characters are shortstacks, not all shortstacks are necessarily voluptuous as long as they are still somewhat curvy.
Not all well-endowed characters are shortstacks.
Not all stocky characters are shortstacks.
Shortstacks characters are usually adults, and should not be tagged as young, cub, or loli
