What does "what a boyfriend" mean here and how can I use this similar expression in other contexts?
"What a boyfriend" in this context means "Wow, I'm impressed" or is showing one's admiration towards a man's actions that benefit his significant other. The man is going above and beyond what is expected of him in a relationship. Rachel's assistant thinks that Ross is so sweet to Rachel by bringing a picnic because it wasn't expected of him. This can be said to a man who you are in a relationship with and it can be used to someone who you aren't in a relationship with. Ex: A: Yesterday, my boyfriend helped me fix my car. He spent all day working on it. B: Wow. What a boyfriend! You are so lucky that he can help you with that. Ex: A: Honey, I got you flowers. B: That's so sweet of you. What a boyfriend.
