A cat that keeps rubbing against you and meowing may want to play with you or beg for food and act coquettishly. You can feed the cat some cat food or snacks to prevent the cat from being hungry. Cats generally like to rub their heads, bodies, or tails against people when they are close to people. If a cat wants to express a certain need, it may rub against people, so you need to observe the cat more to see what the cat specifically wants to express.
