Who made it

Fanum, a member of Kai Cenat’s streaming collective AMP, who jokingly “taxed” his friends’ food on stream from late 2022.

Where it came from

AMP and Kai Cenat streams, then YouTube and TikTok clip channels.

Who usually gets left out

Fanum himself, oddly: the phrase is so often used as nonsense that many people saying it do not know it names a real person.

What Fanum tax means

Literally, to fanum tax someone is to take a share of their food. Asked by WIRED in October 2023, Fanum described it as taking “5%, 10% of the meal, maybe 20%”. It is stretched metaphorically to anything taken unfairly: a sibling borrowing your charger is committing a fanum tax.

Thanks to the parody song, it is also used as complete nonsense (“you’re so fanum tax”), which is how a phrase about fries ends up meaning nothing at all.

Where it came from

The term comes from Fanum, a member of Kai Cenat’s streaming collective AMP. Starting around late 2022, Fanum would burst into streams and jokingly “tax” his friends’ food by taking a bite — a bit that became known as the “Fanum tax”.

It is one of the clearest examples of slang with a named source: a real person, a real running joke, and a fan community that turned it into a rule.

When it was first seen

  • Late 2022: the tax begins on AMP streams, where Fanum helps himself to whatever anyone else is eating.
  • 2023: clips spread through YouTube and TikTok; the phrase becomes a caption on any video of someone stealing food.
  • October 2023: the parody song “Sticking Out Your Gyatt for the Rizzler” bundles it with skibidi, sigma and rizz, and the phrase goes fully mainstream — and fully nonsensical.

How it spread

The vector was clip culture. AMP streams run for hours; their audience lives on the clips, and the fanum tax was a perfect clip — five seconds, one joke, infinitely repeatable in any kitchen.

The parody song then carried it to children who had never seen a stream, which is why Gen Alpha uses it as a sound rather than a rule.

Variations

Fanum taxed: the past tense, applied to any theft. Fanum tax as a nonsense adjective. The metaphor stretched from food to time, money and attention, and then snapped: the word now lives mostly inside slang-overload jokes.

Is it still in use?

Fanum tax is fading — mostly a nostalgia reference now, tied to a specific 2023 moment. The tells: it is rarely used sincerely about food any more, and it is one of the first words listed when people mock brainrot slang.

Our read: fading. The tax is still collected, but only ironically.
