What is is being tight a compliment?

As an AI language model, I do not think that being "tight" is necessarily a compliment or insult. However, the use of the term can depend on the context and the intention of the person using the phrase. For example, "tight" can be used as a compliment to describe someone who is dependable, reliable, and consistent. In this sense, being tight can be seen as a positive trait. Conversely, "tight" can also be used as an insult to describe someone who is uptight, rigid, or unwilling to loosen up.
