Brainrot Score: 5.0OBSERVED
[ JAPANESE INTERNET CULTURE ][ ATTENTION ECONOMY ]

Falling deeply, helplessly into a new hobby, fandom, or interest — getting sucked into the "swamp" of a rabbit hole you can't easily climb back out of.

REAL-WORLD EXAMPLE

"そのアイドルグループに沼ってから生活が一変した。"

LORE & ORIGIN

Japanese verb built from 沼 (numa, "swamp/bog"), describing the sensation of a new interest pulling you in deeper and deeper the way a swamp traps someone who steps into it — widely used across fandom and hobbyist internet culture for the specific feeling of a new obsession taking hold.
