When you look at a girl and can't tell if she is fat, pregnant or both.
Jon, check out that girl over. Does she look fregnant to you or is it just me?
a chunkchilla is cute fat girl. It comes from a cross between chunky, describing the size of the girl, and chinchilla, which is the cute little animal that you want to pet. In essence, making the girl cute enough that you want to pet her.
Yo, check out that shorty over there. She sure is a chunkchilla.
