What do all the cave diving memes mean? If your various social media feeds are full of videos of upside down shoes and boots in different locations, you're witnessing "cave diving" memes.

Cave Diver memes mock the extreme, ... venturing into an unmapped part of the cave. Jones ended up trapped upside down in a 10″ x 18″ space, as a 6 ft. tall, 200 lb. man.

The memes started en masse last week when a TikToker named @bigmoneyjaytee posted a video called, "Cave divers for no reason," showing himself examining the crack between his fridge and floor.
