What do you mean by putting on airs and being fearless?
Personally, I think putting on airs and showing off without fear is the zodiac. Dog zodiac is a fearless animal, known as the most loyal friend of human beings and the pet with the highest reproductive rate. In network language, it is often used as a general term for special or extreme people, and it is put at the end, often with the meaning of ridicule or self-mockery. Such as licking dogs (unconditionally pleasing others) and Yan dogs (willing to love ta as long as the other person's face value is high), Malay dogs (using the advantages set in the game to overuse a skill).
