3x06 Mash Off

Finn Hudson: Hey, Santana! Why don't you just come out of the closet? You know, I think I know why you're so good at tearing everybody else down. It's because you're constantly tearing yourself down, because you can't admit to everybody that you're in love with Brittany and she might not love you back. That must hurt, not be able to admit to everyone how you really feel. You know what I think you are? A coward. See you at the mash off.

Santana Lopez: You seriously think you can out-insult me? I'm from Lima Heights, I was raised on insults. It's how my abuela puts me to sleep at night, and she was not a nice lady. Did you know she tried to sell me once? And it wasn't until I got to kindergarten that I learned my name wasn't Garbage Face.

Rachel Berry: Okay, you know what, Santana? Finn is in great shape and your meanness only highlights your own insecurities.
Santana Lopez: Rachel, your mustache is thicker than a Middle Eastern dictator.
