The term "snowflake" is often used as an insult to describe someone perceived as overly sensitive or easily offended. It suggests that the individual is unique and fragile, much like a snowflake, which can be seen as a criticism of their emotional resilience or ability to handle differing opinions.
This insult gained popularity in the 2010s, particularly in online discussions and political debates. It is frequently directed at younger generations, especially Millennials and Generation Z, who are sometimes viewed as more vocal about social issues and personal feelings compared to previous generations.
