The phrase "suck up" means to act in a flattering or insincere manner towards someone in order to gain their favor or approval. It is often used in a negative context, implying that the person using this tactic is being manipulative. For example, if someone is constantly complimenting their boss in order to get a promotion, you might say they are "sucking up" to them. It's usually not a positive thing to do, as it can come across as fake and dishonest.
