The expression "cosy up to" means to become close or friendly with someone, often with the intention of getting something from them. It can also mean to position oneself comfortably close to someone or something. For example, you might say "She's trying to cosy up to the boss to get a promotion" or "He's cosied up to the fireplace with a warm blanket and a good book". It's a casual way of describing someone who is trying to get closer to someone else, either emotionally or physically.
