Re: Too true
I find asking people what they mean by (eg) 'onboardification', and then quizzing them on why they didn't just use a real word tends to reduce the amount of bollocks they come out with. If that doesn't work, start writing a 'bizspeak to English' dictionary in front of them, and make a big show of consulting it to translate each sentence that comes out of their mouth.
You should be able to effectively de-rail the meeting and get back to doing real work within half an hour or so. Bonus points if the sales person leaves in tears.
