ELI5: What does the phrase "needs more jpeg" mean exactly?

I was under the impression jpeg was a file format. How does it relate to degraded image quality compared with other formats?

JPEG is a "lossy" compression format, meaning that the image loses information/quality every time that you save it. So, if a JPEG is saved dozens of times by different people, it tends to look pixelated and blocky from the compression algorithm.

So, "Needs more JPEG" is a sarcastic way of saying "This image looks awful from being compressed so many times".

Different file formats compress images differently. Some are "lossless", meaning that the quality does not degrade every time you save it.
