Fanum Tax definition: what "Fanum Tax" means and examples

The act of jokingly stealing a small portion of a friend or family member's food, usually a single chip or bite.

This originated from a streamer named Fanum who would "tax" his friends' meals. It has become a household term for that cheeky moment when someone swipes a bit of your dinner just because they can.

Examples:

  1. "You ate half my burger! That is way more than a Fanum Tax."

  3. "Dad always claims the Fanum Tax when we order pizza."
