意味

To fall deep into an obsession or hobby and become unable to stop — the verb form of the 'swamp' metaphor.

A verbified form of 沼 (swamp), 沼る means actively sinking into an obsession. While 沼 is a noun describing the state, 沼る is the action of getting sucked in. It is newer slang, primarily used by younger speakers on social media. The る suffix turns the noun into a verb following a productive Japanese slang pattern (like ググる from Google).
