A commenter on Dr. Sanity's blog says that this is the modus operandi of half the politicians and 90% of the American media. It explains their entire attitude toward those who wield power in this country. It's an acronym, of course; it stands for Now I Gotcha You Son Of A Bitch.
Nothing matters to these people except finding something that will take down their target, and that's what they always aim for. Find a topic, gun for it with both barrels, and if that doesn't work, move on to another angle and attack from there. And when you find something that goes through their armor and actually opens a wound, lean on it as hard as you can. Now I gotcha, you son of a bitch.
