Similar to other silly terms used to describe cute animals (like doggo), chonk is a made-up word to classify fat cats. It is not typically used as an insult, but rather as a term of endearment.

The “Chonk Chart” is a popular meme that was originally posted to the Facebook group “THIS CAT IS C H O N K Y” by Emilie Chiang:

Internet users have also applied the term to other animals:
