Julianna FriskYou may have come across the terms Shitadel or Mayo Man on Twitter or Reddit and wondered what people are actually referring to.
Shitadel is a slang nickname used online for Citadel LLC, an American hedge fund and financial services company founded by Kenneth Griffin. The term is a blend of the word “citadel” and a crude insult, commonly used in a critical or mocking context, especially within retail investor communities.
Mayo Man
Mayo Man is another nickname aimed at Kenneth Griffin. It comes from a widely shared online anecdote in which he allegedly refused to share mayonnaise during a dinner. Whether the story is factual or exaggerated, the nickname stuck and is now frequently used as shorthand for Griffin himself in memes, comments, and discussions.
Both terms are part of internet slang rather than formal financial language, and they’re mostly used in online conversations critical of hedge funds and institutional finance.
