The 'Invest In Rare Fish' and 'Multiple Uncles' meme is a surreal parody of 'Sigma' motivational speakers and grindset culture influencers who provide unsolicited and often bizarre financial advice. It typically features a serious-looking man explaining why rare fish are the ultimate asset class or claiming he has 'multiple uncles' as a source of wealth or wisdom. The trend gained massive traction on TikTok and Instagram Reels in late 2022 and 2023, often accompanied by slowed-down phonk music. It mocks the absurdity of get-rich-quick schemes and the hyper-specific, nonsensical logic sometimes found in the 'hustle' corner of the internet, turning confusing business jargon into a comedic masterclass in irony.
