Some people keep saying that I am a pig, how should I refute=. =Ask for help

Calling you a pig is not necessarily a bad thing. Since I can say this about you, it proves that I am a really good friend of you.

You see how hypocritical people outside are now, and they want to treat you like a pig. I praise you to the sky, and then I wonder how I will scold you behind my back

Next time I say you are a pig, just reply: "Well, that must be a cute pig." It's a joke, so why not respond in a joking manner?
