Snowflake is a derogatory slang term for a person, implying that they have an inflated sense of uniqueness, an unwarranted sense of entitlement, or are overly emotional, easily offended, and unable to deal with opposing opinions. The term gained prominence in the 2010s, and was declared by The Guardian in Britain to be the "defining insult of 2016", a term "thrown around with abandon in the wake of Brexit debate in the United Kingdom and the 2016 US election".

Common usages include the terms "special snowflake", "Generation Snowflake", "Snowflake Generation" and "snowflake" as a politicized insult. In the past, it held different meanings in reference to white people.
