gigantic ass

Definition

A descriptor for characters with an extremely large, exaggerated, or unrealistic butt size that dominates their proportions.

Usage

Use this tag when the character’s butt is depicted as absurdly large, disproportionate, or clearly beyond realistic anatomy.

Do not use if the size is not described or is within normal proportions.

For a size that is extremely large, but within the realms of possibility; use huge_ass.
For a size that is described as just above average or big; use large_ass.
For smaller sizes below average proportions; use flat_ass.
