(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.

Chonk is an internet slang term used to describe overweight cats that grew popular in the late summer of 2018 after a photoshopped chart of cat body-fat indexes renamed the "Chonk" scale grew popular on Twitter and Reddit. Additionally, "Oh Lawd He Comin'," the final level of the Chonk Chart, was adopted as an online catchphrase used to describe large objects, animals or people. It is not to be confused with the Saturday Night Live sketch of the same name.

The original chart has a copyright date of 2012, so the meme dates back to at least that far.
Man 1: The top definition for "Chonk" as of writing is incorrect about the origin of "Chonk".
Man 2: Oh word? Well, I guess it's my job to fix whatever the fat chonky asshole who posted it screwed up.

A usually very morbidly obese animal which people think is cute. the word chonk is a morphed version of chunk.
dnt worry though, chonks usually get better and become normal (still cute) animals. theres also subreddit on reddit called r/chonkers and another one where chonkers get healthy.
