The expression "once removed," "twice removed," etc. is used to talk about family relationships. It means that someone is related to someone else, but they are not directly in the same generation. For example, your cousin's child is your first cousin once removed because they are one generation below you on the family tree. If your cousin's grandchild is born, they are your first cousin twice removed because they are two generations below you. The phrase is used to show the degree of separation between family members.
