About the "snowflake" term, which has its origins in Fight Club

Kids these days... You think nothing existed before you were around.

Fight Club’s snowflake, though, isn’t its earliest instance as an insult. During the Civil War in Missouri, pro-slavery advocates were called snowflakes for valuing white people over black people. (That’s a diss we can get behind.) Over a century later in the 1970s, black people who were seen as acting too white were mocked as snowflakes. The idea, here, is whiteness—like snow. Fight Club, nevertheless, did help to spread snowflake as a contemporary insult online in the 2000s to tease sheltered, helicopter-parented, everyone-gets-a-trophy young adults. The core metaphor is that such people are delicate like snowflakes, easily hurt by the hard realities of life, and think of themselves as special without realizing they are entitled and privileged— because every snowflake is different, as they say.
