I joked with my girlfriend that no matter how fat you are, I don't want you. She said, what you don't want, others want.

Sometimes joking between boyfriends and boyfriends can not only strengthen interaction and enliven the atmosphere, but also become a mediator of love.

However, joking should not only pay attention to the grasp of "degree", but also have a broad mind and acceptance. Otherwise, it is best to joke less, because it is easy to hurt feelings.

Just like you joked with your girlfriend that "no matter how fat you are, I don't want you", which is a bit excessive, and her sentence "You don't want someone" obviously has a self-defense mechanism, which is not as easy as you think. I'm afraid you'll be uncomfortable after hearing it. Therefore, we must grasp a degree of joking in order to form a benign interaction.

Of course, if both male and female friends are big-minded and don't care about the joke content at all, that's another matter.
