My mom's cousin is my what?

Your mother's first cousin is your first cousin once removed. Your mom and her cousin share grandparents; you are one generation below your mom, creating the single-generation gap that 'once removed' describes. Many families call this relative an honorary aunt or uncle, but the precise term is first cousin once removed.
