What is the psychology of people who like to curse?

Such people may be relatively impatient inside. Generally, they are impatient, and then they demand perfection excessively. If others can't meet his requirements, they can't stand it, care too much about each other's behavior, and then want to call names.

In fact, sometimes it's because I'm emotional and can't control my temper. Some people may still feel guilty after scolding, but they can't help it.

Such people are generally more competitive and individualistic, and are less likely to consider problems from the standpoint of others.

If it is between friends, the best way is to communicate with him properly. So as long as you know them, you probably know what kind of personality they are.
