General:
"I had a lovely train of thought going there and not only did you stop it, you hijacked it, derailed it, and sent it spiraling off a bridge. You are a train of thought terrorist."
"What do you mean you're not a US citizen? You?re Canadian. That?s like a step away from being Alaskan."
"Do you see all of this damn I am giving?"
"What we need is a morally ambiguous third option!"
Gaming:
"You have this terrible habit of NOT BEING DEAD!"
"You suck because you're dead because I killed you!"
"You appear to be sucking. I suggest not sucking so much. That will help you suck less."
"I only allow you to live because you amuse me!"
My incompetent chemistry lab partners tend to invoke my wrath a lot:
"You are undeserving of the air you breathe!"
"We both used the same formula but got different answers. We don't have time to check. You're an idiot, so we're going with mine."
"I will tear out your throat with my teeth."
"Well that makes you an idiot"
"Either do something useful or kindly step away and die."
