The definition of a karen is a white woman who feels she is entitled to anything she wants, and bosses around whoever she wants. She once got really angry over the fact our pizza box was not folded perfectly. I dropped my binder on her lap after she yelled at me to give it to her, and she locked me outside in the cold until I just decided to walk to my grandmother's house, threatened to throw away my blankets, and told everyone that I, unprovoked, threw a binder at her, and then walked out the door with no events leading up to that.
