Snowflake is jargon that refers to a sensitive person who is too easily insulted.

Some people use the term snowflake to describe extreme liberals, others use it to describe millennials, but basically it refers to someone who gets offended by every statement and/or belief that doesn't exactly match their own. For example "The university set up a virtual tent for snowflakes who can't deal with any kind of opposing opinion."
