Special Snowflake Syndrome (also known as Speshul Snowflake) is a psychological phenomen of Generation Y, where the people suffering from it seem to live under the illusion that they are special for doing things that are stereotypically considered "lame" or childish, like drinking through a funny-straw or building forts. More often than not they are in High School (though it's not uncommon to find them on college campuses also) and are recognized by the way that they condemn their peers for drinking and partying and whoring around, whereas they're preserving their childhood innocence and being original by watching cartoons and still cutting the crust off their sandwiches. They are also known as the First Form of Hipster.
While all my other classmates are out getting shitfaced at parties and sleeping around, I built a fort out of pillows and blankets in my bedroom and had a Lion King Marathon (because Lion King is like, awesome) while eating cereal. I am such a special snowflake.
