Threadjacking, the art of deliberately diverting an online discussion away from its original topic, became a staple of internet culture in the early 2000s on forums like 4chan and Something Awful. The most iconic version involves the phrase 'This thread is now about...' followed by a jarringly unrelated subject, often accompanied by a picture of 1960s Spider-Man or obscure hobbies like trains. It serves as a humorous way to signal that a conversation has become boring, toxic, or simply needs a chaotic change of pace. Today, it remains a popular tactic for lighthearted trolling and community inside jokes across social media platforms like Reddit and X, allowing users to assert dominance over a comment section with absurd and unexpected content.
