The expression "rub in" means to apply pressure to something while moving your hand or fingers in a circular motion. This is usually done when you want to make something absorb into the skin or object better. For example, if you are applying lotion to your body, you would rub it in by massaging it into your skin. Another example is when you are seasoning meat, you would rub the seasoning into the meat with your hands to make it flavorful. It is important to use this expression correctly as it can change the way the particular product or substance acts.
