What does Fanum Tax mean?

Fanum tax is the "tax" a friend takes from your food — named after streamer Fanum of Kai Cenat's AMP crew, who jokingly taxes a bite of whatever his friends are eating. It went viral in 2023, was immortalized in the "Sticking Out Your Gyat for the Rizzler" song, and remains a staple brainrot reference.

On stream, Fanum would walk into Kai Cenat's room and take a portion of his food as a mock toll. Clips of the bit spread through TikTok until "fanum tax" became universal shorthand for snack theft between friends — "he fanum taxed my fries."

It is one of the defining brainrot-era terms, frequently strung together with skibidi, rizz, and gyat in deliberately nonsensical sentences. Sincere usage still works for food content and friend-group humor, and food brands have leaned on it with varying success.
