asshole voice
The voice you use when you're talking about someone you don't like in their own dialogue. Sometimes a slower, deeper, more stupid-sounding voice than your own for someone you think is an idiot, or a higher-pitched whine for someone who thinks they're better than you are.
I was talking about Zombieland yesterday and Don said, (friend voice)"It was awesome." But Larry came up and was like, (asshole voice)" Yeah, I didn't get it. All these zombie movies are really stupid."
