Having a naturally high capacity for fat cells within the body while maintaining a normal human shape; usually resulting in a round face, curvy figure, and a softer, thicker body.

Different from "Fat", where the number of fat cells within the body exceeds the body's natural carrying capacity, thus forming cellulite, rolls, etc. as the body no longer has space to store accumulated lipids.

A person may be fat, chubby, both, or neither.
"I love her chubby cheeks: it makes her baby face even more adorable!"

"I knew you liked fat girls!"

"What? She's not fat, she's chubby... No rolls."
