What is the definition of Gallery Infection?

A 'gallery infection' is like when an art exhibit gets a bit too cozy and starts attracting unwanted visitors - but not the kind you'd expect, like creepy-crawlies or bad art enthusiasts. Instead, it's more of a metaphorical term for a situation where an overabundance of art, whether it's paintings, sculptures, or even just bad memes, invades a space and makes it feel like an uninvited, but oddly charming, art party gone wrong.

Here's a edgy example sentence: "The gallery's 'gallery infection' spread like wildfire, turning our once-gracious space into a haunted art museum where the only guests were our collective guilty pleasures and the occasional creepy-crawly that thinks a Picasso is its masterpiece."
