Well an Emo is not just about one characteristic. An emo encompasses things such as the way they dress, the music they listen to, the way they act, and their culture. It actually started as early as the 1990’s. Most people would call a person an Emo if they wore skinny pants, tight band t-shirts, punk hairstyles, and black studded jewelry. The type of music is generally on the punk side as well. And not all but some Emo’s, may appear to be introverted and emotional.
