What is what does it mean when a girl says you look good?

When a girl says you look good, it generally means she is complimenting your appearance. This could pertain to various aspects such as your clothing, grooming, hairstyle, or overall presentation. Compliments like this often aim to be polite, encouraging, or flattering. Here are a few possible interpretations:

1. Genuine Compliment: She might genuinely think you look nice and wants to acknowledge it.

2. Confidence Boost: It could be an attempt to boost your confidence, particularly if she knows you might be worried about how you look.

3. Social Courtesy: Sometimes, people give compliments as part of social niceties without any deeper implication.

4. Interest or Attraction: In some cases, it could imply that she is attracted to you or interested in you, though this would generally be accompanied by other signals or context.

5. Friendly Gesture: It might just be part of a friendly interaction to maintain a positive and comfortable social setting.

Understanding the intent behind the compliment can depend on the broader context of your relationship, her tone of voice, body language, and the situation in which the comment was made.
