Community was a hilarious show, but it showcased some horrible moments between the members of the study group and Britta.
The first person to call Britta the worst was Señor Chang in season one when she mispronounced the word "bagel". From there, the catchphrase took off and Britta became known as the worst, aka the AT&T of people, the human tennis elbow, the pizza burn on the roof of the world's mouth, and the opposite of Batman. "To britta" something even became a synonym for messing up.
