What does it mean to call your girlfriend Lafayette?

It may be a funny nickname, or it may be the love for his girlfriend in his heart, suggesting that his girlfriend is very important in his heart.

It may be that in love, the woman is usually stronger and has a higher status than the man, which is a joke of the man.

On the whole, it's definitely not a bad thing to call Galeries Lafayette. That's what I call my wife. However, Chinese is an imprecise language, and the meaning of the same word can be completely different in different contexts, depending on the environment and expression at that time.
