A word that I had seen before but wasn't really sure of the definition—blagging. Dan Sabbagh and Ewen MacAskill, in an article headlined ‘I was nothing more than a common thief’, define it as using subterfuge to obtain private information from banks, mortgage companies or utility firms. But they don't get around to doing that until a dozen paragraphs and half a dozen uses in, curse them.
The OED doesn't really have that definition yet, it seems. It's a specific variant of what they do have, which is to obtain or achieve by persuasive talk or plausible deception. I wonder whether the more specific sense will stick, or will drive out the more general one.
The derivation is presumably from the French, but I wonder if perhaps the word blagger was taken up so rapidly (it seems) under the influence of blaggard, or blackguard. At any rate, it's a wonderfully contemptuous-sounding word, innit? Blagger. Nobody wants to be a blagger when they grow up.
