What is fanum tax?

Fanum Tax is a slang term popularized on Twitch and YouTube, mainly by Kai Cenat and his AMP (Any Means Possible) crew. It refers humorously to the act of taking a portion of someone's food or belongings, presented as a mandatory "tax" for being in the presence of someone famous or powerful, or simply because someone wants it.

The "tax" is usually taken playfully and is often done without asking. The person having the tax imposed upon them is expected to comply, although they may jokingly protest. The trend is often associated with Gen Z culture and internet humor. It is generally considered lighthearted but can be seen as annoying if done excessively or without consideration for the other person's feelings.

The term itself has no real-world or financial relevance; it is purely a comedic expression within the context of online communities and streaming culture. Its popularity surged through viral clips and challenges across social media platforms.
