ELI5: How do subcultures like punks, juggalos etc. get popular and make people change their lifestyle?

It's an aesthetic. You wear the uniform, and instantly you identify yourself to other people who take issue with current societal behavior or whom wish to express a part of themselves - many of these subcultures have room for individual creative experimentation within the basic tropes.

The music is often angry, and it explores subjects taboo for children. Murder. Sex. Evil. Injustice. It can unite those who come from sheltered backgrounds, or those who survived Hell on Earth. Largely, it starts appealing in adolescence. In a time when your emotions are intense, and your worldview not expansive, it's often very introspective in a way that seems self-absorbed or even threatening to older people, but seems more real... 

Also, the many cultural revolutions these styles have created have done wonders for getting us to be more accepting of one another. 

It used to be that not fitting in was asking for violence, or imprisonment. Now, those who wish to take part may, visually at least, leave the herd, and those offended dismiss it as being a snowflake. Most Westerners simply don't care. 

Human culture evolves, in tiny, insignificant steps.
