What is when a guy says you smell good?

When a guy says you smell good, it means that he likes how you smell and he finds your scent attractive. It could be because of the perfume or body lotion you are wearing or just your natural body odor. Complimenting someone's scent can be a way of showing interest or admiration towards them. However, it is important to pay attention to the context and the person's intent behind the compliment. It is also important to note that some may find unsolicited comments about their scent uncomfortable or inappropriate.
