What should I call my best friend?

Or: spare tire, candidate

Man to man: gay friends.

A man's best friend refers to a close male friend who can have a good relationship with you, go shopping together and share everything carefully, but is not a couple. A man's girlfriend is the kind of girl who talks about everything and is loyal to each other. Women regard it as their "opposite sex confidant". You can talk to them when you are wronged, talk to them when you are upset, and even consult them when you are preparing for the first date with your new boyfriend. They can also have heterosexual partners with each other, and their heterosexual partners also know their relationship.

Most girlfriends are the ones who discuss with you the most, such as physiology. Therefore, boudoir is generally synonymous with girls. Now, with the progress of society, more and more girls impose this synonym on boys.
