A meme popularised in Tiktok and Instagram in 2025, based on the hobby of cave exploration. It usually shows either a pair of feet sticking out of a hole, or a silhouette of a spelunker stuck upside down in a narrow hole (based on the death of John Edward Jones in Nutty Putty Cave).
It should be noted that the name is misleading, as cave diving refers specifically to exploring underwater caves.
