Toxic Chill Girl
Popularized by internet personality Hannah Montoya, the "Toxic Chill Girl" tries to act cool, calm and collected, with the aim of trying to present herself as superior to others. She simultaneously insults and degrades others in indirect ways, often times by belittling things they find interesting or exciting.

Toxic Chill Girl: "That movie was so bad, actually. And can you, like, calm down? You're like, literally yelling."
