The comedy Mean Girls is about a girl named Cady who moves to Evanston after being home schooled while living in Africa. Cady then has to experience high school with barely any knowledge of what teenagers act like. She then meets the Plastics, a group of popular mean girls. Satire is shown throughout both Cady's little knowledge of high school life and of the Plastics meanness to everyone else at school.
One example of dramatic irony is when Cady first arrives at high school. She does not have any experience with high school or any school since she has been home schooled her whole life. When she arrives in the cafeteria on her first day she approaches a group of african american girls. Cady thinks they will be welcoming and says "Jambo" thinking they will become her friends and let her sit. Instead however they stare at her with an unfriendly look. This scene is an example of dramatic irony because the audience knows the girls will probably not know what Cady is talking about and most likely think she is weird. Another example of dramatic irony is when Cady does not get the slang of the high school girls. When Cady tells Regina that she has always been home schooled Regina goes on to say "shut up! Shut up!" to which Cady replies "I didn't say anything." This scene has Cady unaware that when Regina says shut up she does not mean literally but just that she cannot believe what Cady is saying. These examples of dramatic irony exagerrate what a home schooled kid knows about society and brings in comedic relief.
The Plastics use verbal irony to put down the less popular girls of their high school. When Regina George, the leader of the Plastics, sees a girl in a skirt she does not like she says "I love your skirt! Where'd you get it?" The girl who is oblivious to Regina's sarcasm says "It's my mom's old skirt from the '80s." Then Regina says "Oh, vintage,so adorable." However, after the girls thanks Regina and walks away Regina comments on how much she dislikes the skirt. This sarcasm is used by Regina to offend the girls of lower social status and to insult people without having the person know they are being insulted. After this scene is shown Cady realizes that when Regina said she liked Cady's bracelet Regina was really using sarcasm. This realization shows that Regina uses sarcasm to insult people without their knowledge.
Overall, the Creators of Mean Girls use irony to make scenes comedic. However, irony especially verbal irony is also used to comment on how much girls insult people behind their backs. Irony is used in Mean Girls to portray the back stabbing and insults from girls to other girls around the world.
