Maybe they think the way they walk is cool and handsome. To tell the truth, I can't understand this weird aesthetic. Maybe they have their own style.
These guys are walking down the street together. They feel that they are left in this world, independent and incompatible with the turbid human beings. So they rebelled and hoped to have some influence in this society, but they made a mistake. In our eyes, their behavior is "non-mainstream". They don't follow the society, stand still, don't know how to look forward, and just stay in their previous thoughts.
Most young people in society are in their twenties. They have not received a good education, and they have not received proper training in "Three Views". It can be said that they are actually naive and funny.
