(noun) First seen in an Internet meme that began circulating circa summer 2018, the word “chonk” refers to an aggressively chubby housecat.

According to the cat girth scale depicted in the meme, a cat is a chonk (or chonker) if it has between 30 and 60 percent body fat.

Variations: chomk, chonker, heckin’ chonker
My cat, Snowball, cries for food and tricks my family members almost daily into feeding her more than once... she’s becoming quite the hefty little chonk.
