Fanum Tax is a term that has recently become popular on social media, particularly on TikTok. It was coined by the comedy creator Fanum, who is a member of streamer Kai Cenats influencer crew AMP. The term refers to the way Fanum would jokingly "tax" other members of AMP in 2022 by taking bits of their food when they were eating. The phrase is used anytime someone wants to yoink your food, and it has since picked up in popularity, garnering millions of views on TikTok. The phrase has also spawned a song called "Sticking Out Your Gyat for the Rizzler," which is a mash-up of Gen Alphas favorite slang terms sung to a catchy tune. While the term is popular with both Gen Alpha and Gen Z, some Gen Zers have created parody videos using "Fanum tax" as an example of how bizarre they feel Gen Alpha slang has become.
