This line is spoken by Gretchen Wieners, played by Lacey Chabert, in the film Mean Girls, directed by Mark Waters (2004).

High school friendships aren't made in the classroom—they're made in the cafeteria.

Cady Heron, the new kid at school, is invited to sit at "The Plastics'" table, a.k.a. the Queen Bees of the school. It's an unprecedented honor for a newbie, but apparently she's pretty enough, according to the Plastics' leading lady Regina, to sit at their table.

Regina's minions, Gretchen and Karen, are just asking the run-of-the-mill getting to know you questions, but Karen's a little ditzy. Come on, everyone knows a Karen in high school. Luckily, Gretchen Wieners is there to remind her about question-asking etiquette.

Where you've heard it

Maybe the Plastics should have added "the think before you speak" rule to their cafeteria code of conduct. But maybe not, since Karen's slip-up spawned many an amazing meme, from Lord of the Rings, to Harry Potter, to Olympic athletes, to Disney princesses.

Vampire fans will appreciate this Twilight/Supernatural mashup. And aspiring politicians get a meme, too.

Pretentious Factor

If you were to drop this quote at a dinner party, would you get an in-unison "awww" or would everyone roll their eyes and never invite you back? Here it is, on a scale of 1-10.

Now serving political correctness for lunch! Just kidding. This one just falls under common sense.
