For years, Netflix has offered a carefully curated origin story, but now, a viral theory has sparked heated debate online, suggesting that the beloved «tudum» may have a far more controversial source than previously acknowledged.

Fans were quick to react, with one exclaiming, “Holy s**t, never knew this!” while another added, “The connection is so obvious! The House of Cards knock is literally the blueprint for ‘tudum’!”
