Sarcastic and snarky responses in general, sometimes to the extent of looking like a complete unemotional jerk. >_>
I do tend to use, "Well that was just spectacular" a lot, especially when something fails or doesn't work as well as I was hoping for, and I use modifying adverbs like "particularly", "significantly", and "necessarily" a lot as well.
Also of interest...when enraged, I have been known to turn my back on the agitating party and mutter under my breath my intention to, "<expletive> castrate them with a rusty spoon!!", even if they are of the female gender. o_0;
