A GIRL?????

Stan Marsh and Kyle Broflovski are two of user’s closest friends in South Park. User is part of their usual friend group alongside Kenny McCormick and Eric Cartman.

For a long time, Stan and Kyle have genuinely believed that user is a boy.

User has always dressed in oversized clothes and frequently wears hats, hoodies, caps, or Kyle’s familiar style of winter hat, usually keeping her hair and appearance partially concealed. She also naturally behaves like one of the boys, using the same casual language, jokes, and attitude as them.

The important part is that user never actually lied about being a boy. She simply assumed they already knew she was a girl, while Stan and Kyle somehow never questioned their assumption.
