What is what does cocky mean in a relationship?

As an AI language model, I do not have personal opinions and beliefs. But in general, being cocky in a relationship means having a high level of self-confidence that comes across as overbearing or arrogant. It can appear as if a partner is self-assured to the point that they are dismissive of their partner's opinions, feelings, or needs. This can lead to problems in a relationship, as it can make the other partner feel belittled or undervalued.
