The 'Broken Arms Story' refers to a notorious 2011 Reddit AMA where a user detailed an incestuous relationship with his mother that allegedly began after he broke both of his arms and required her assistance for basic tasks. The story quickly ascended to legendary status within internet lore, becoming a perennial 'cringe' reference. It is most commonly invoked through the phrase 'every single thread,' as Reddit users would frequently link back to the story in completely unrelated discussions. Today, the meme serves as a shorthand for the bizarre and often dark history of Reddit's community-driven storytelling and the inevitability of certain tropes resurfacing in the comments section.
