What is Gemini Favourite body part?

I'm curious to understand, in the context of the cryptocurrency exchange platform Gemini, what could possibly be meant by "Gemini's Favourite body part"? Typically, such a phrase doesn't directly relate to financial institutions or cryptocurrency exchanges. Is there a specific context or reference I'm missing? Could this be a joke or a misinterpretation of some information? If there's a deeper meaning or reference to a specific aspect of Gemini, I'd appreciate some clarification.
