The 'This is Now A Spiderman Thread' meme is a legendary internet derailment tactic that originated on imageboards like 4chan in the mid-2000s. It typically features low-budget, often surreal screenshots from the 1967 Spider-Man animated series. When a thread became boring, off-topic, or toxic, users would post these images to signal a complete takeover of the conversation, effectively replacing the original discussion with a flood of nonsensical Spider-Man captures. This meme capitalized on the awkward animation and unintentionally hilarious poses of the vintage show, solidifying the 60s Spider-Man as an enduring staple of internet subculture and forum hijacking.
