The expression "butter up" means to flatter someone in order to get them to do something for you or to make them like you. It's often used when someone wants to persuade or influence another person. For example, if you want your boss to give you a raise, you might start complimenting their work and saying nice things about them to "butter them up" before bringing up the topic. It's important to use this expression in informal situations, as it can come across as insincere or manipulative in more formal settings.
