Why is Munich 1860 called cousin by Bayern fans?

In fact, the word cousin was originally used to refer to AC Milan, not only by China fans, but also by fans all over the world. Needless to say, in Italy, because Inter Milan and AC Milan used to be a team with cousins. Inter Milan's main color is blue and black for masculinity, and one meter's main color is red and black for femininity. The word team is feminine in Italian, so one meter is called cousin.

Later, cousin and cousin were used to refer to two teams in the same city, such as Bayern Munich and Munich 1860, Manchester United and Manchester City.
