When we talk about ourselves, we use words like "I" or "me". When we talk about someone else, we use words like "he" or "she". Sometimes people don't feel like "he" or "she" fits them well, so they might ask others to use a different word, like "they" or "ze". This is what a Spivak pronoun is - a word that someone chooses to use instead of "he" or "she" to describe themselves. It's important to respect other people's choice of pronouns, even if they might seem strange to us.
