Why is slipstream a girl?

Excuse me, could you please elaborate on the statement "Why is slipstream a girl?" It's quite intriguing, but I'm not entirely sure what context you're referring to. Is "slipstream" a particular cryptocurrency, a project, a character in a story, or something else entirely? The reason I ask is that the term "slipstream" itself doesn't inherently have a gender associated with it, so I'm curious to understand the context behind your question. Perhaps you could provide some more details or clarification to help me better understand your inquiry.
