And another one:

Sorry you scared me. It must be that you look like Samara from the Ring. And I'm talking about the part where she crawls out of the TV with her jacked up face.

Yet another:

There are a lot of problems in the world. Most of them have to do with the people.

Annnddd... another:

What did you do with your hair today? It's hideous.

And even more...:

You must be drunk or high because that's the only explanation for your stupid reasoning.

Let's keep going I'm on a role!

It's not you, it's me. Just kidding it's you.

Oh boy even more from the queen of sass:

If you think about meeting yourself and find yourself imagining punching yourself in the mouth, that's a hint to work on your personality.

Oh I love this game:

I have no idea what you just said. I usually stop paying attention right as soon as you draw breath and open your mouth.

A/N: Sorry I got a bit carried away... I love insults. In fact I almost used a few Shakespearean ones but decided to be original. Enjoy these xD
