When men say dopamine, they usually imply the following:
1. Have a favorable impression of you: Dopamine plays an important role in the human body, especially in terms of emotions and desires. When a man says dopamine to you, it is likely to imply that he has developed some emotional attraction or fondness towards you, similar to a feeling of heart or liking. This emotion is often accompanied by the secretion of dopamine, which makes him feel happy and excited.
2. Hope to establish a closer relationship with you: Since dopamine is closely related to human desire and feelings, men may also express their desire to establish a closer relationship with you, such as a romantic relationship. He may be expressing his interest and expectations in you implicitly through this way.
3. A metaphor or joke: In some cases, when men say dopamine, it may just be a metaphor or joke used to describe something exciting or pleasant. For example, he may use the phrase 'you're really my dopamine' to describe the happiness you bring him, but it doesn't necessarily mean he has a deep emotional commitment to you.
Due to the existence of context and individual differences, the specific meaning of dopamine that men say may vary from person to person. When understanding this suggestion, it is best to make a comprehensive judgment based on the specific context and the man's other words and actions.
