Alstonitis

Alstonitis, also known as Alstonism, is an obsolete term used to describe the "affliction" of a furry character (usually female) depicted with huge breasts, teats, or mammaries which fail to display any effect in regard to gravity.

Term's origins
The term stems from observations regarding the work of greymuzzle furry artist Scott Alston. Alston himself found the term "offensive" to his family name.
