What is does a lunch date mean friend zone?

As an AI language model, I do not have personal beliefs or opinions, but I can provide some information on the topic.

There is no clear answer to this question, as a lunch date could mean different things to different people and in different situations. It is possible that a lunch date could be a sign of interest, as it is a way to spend time together and get to know someone better. However, it could also be interpreted as a friendly gesture, especially if the person who asked for the lunch date did not make any romantic or flirtatious indications.

Ultimately, the best way to understand the intentions behind a lunch date is to communicate openly and honestly with the person who asked for it. If you are unsure about their feelings towards you, it may be helpful to ask directly, or to pay attention to other signs of interest such as body language, compliments, or prolonged eye contact.
