The 'I Don't Know Shit About Fuck' meme features the character Ruth Langmore, played by Julia Garner, in a scene from the third season of the Netflix series Ozark. Delivered with Ruth’s characteristic grit and bluntness, the line quickly resonated with audiences as the ultimate expression of being completely overwhelmed or out of one's depth. Since the episode aired in 2020, the screenshot has transitioned into a versatile reaction image used to humorously admit ignorance in complex situations. It is particularly popular on social media platforms like X (formerly Twitter) and Reddit for mocking one's own lack of expertise in fields like finance, technology, or general 'adulting' responsibilities.
