According to OxfordDictionaries.com: Snowflake is a person, especially a young person, viewed as lacking resilience and being excessively prone to taking offence.
The well-established definition is someone, young or old, that is delicate, fragile, sensitive and melts at the moment heat is applied. Marooned in a kind of no man’s land between adolescence and adulthood, with the associated fibbing and delusions. Some people refer to them as Generation Y, others as the millennials. The favoured title for today’s young folk, though, is the Snowflake Generation.
Generation Snowflake, or Snowflake Generation
Terms usually applied to youths who became adults in the 2010s, otherwise they are middle-aged Libtards; more prone to taking offence and less than resilient. Emotionally vulnerable and unable to cope with views that challenge their own. Some grow up (or rather age) to be LibCons.
Such youths are addicted to mobiles and social media and not particularly good at communicating with members of other generations, either socially or in the workplace. May be religious or virtuous, usually idealistic, adolescent and naive.
Their immersion in social media toxic bubbles has accustomed them to just communicating with their peers. It’s difficult to grow up if you have no idea how to talk to grown-ups. On the other hand: embarrassing middle-aged Liberals never seem to grow up; they make Hyacinth Bucket look like a fascist swinger (copyright Bryony Gordon, 2016).
