The phrase plays on the long running Now That's What I Call Music compilation wording, twisted here with the internet slang thicc for exaggerated thickness. The exact original recording is unclear, but the clip spread through meme soundboards and short video edits as a reusable reaction line. It stays popular because the wording is instantly understood without context, fits gaming, anime and pet videos alike, and gives editors a clean vocal punchline for any reveal that is meant to look comically large.
About this sound
A short voice clip saying now that's what I call thicc, used as a funny reaction when a character, pet or object looks extra thick in a meme edit.
This is a brief, exaggerated voice line that delivers the phrase now that's what I call thicc with playful emphasis on the final word. The speaker sounds amused and impressed, stretching the delivery so the joke lands like a punchline rather than a normal comment. At just over two seconds, it works as an instant reaction to a visual reveal, especially anything comically oversized or curvy. The humor comes from treating thickness like a quality worth celebrating, which makes an ordinary image feel deliberately over the top and meme ready.
