The unwritten rule where a friend, when in close proximity, is entitled to a small portion or "tax" of whatever you are currently eating or drinking.

Fanum Tax was started whenever a big morbidly obese black man named Fanum joined the stream-house called AMP, in these streams Fanum would walk up to his friends and he would tax their food, by taxing I mean stealing, this quickly became a meme, and now it is commonly used among over "Brain-Rot" phrases, such as: Skibidi Toilet, Grimace Shake, Mewing/Mogging, Edging/Gooning, ETC.
"Michael Stevens did you see the Fanum Tax on the last stream?" "No kitten, I was too busy drinking a special someone's milk."
"Dude, my little brother Fanum Taxed me." "What the actual fuck is Fanum Tax?" "Please eat out my asshole."
"Skibidi Toilet, Fanum Taxed my little brother while he was edging, and the entire time the Skibidi was mewing." "Actually kill yourself."
