Definition: Unslim! Unslim is a word that has been around for centuries, but it's only recently gaining popularity due to its playful and humorous use.

And here's an edgy example sentence: "Remember that time I had dinner with my friend and we were all laughing about how 'unslim' he looked. And I said, ‘oh, no, that guy is unslim! He's actually very thin!' "
