I guess you're not working in an office as in Management - I tell you I had to litteraly hold myself back in some meetings not to fucking strangle some people.
Here are some of the best things I have heard over the years:
1) Soaking up the business
2) Blue skying
3) Silver bullet
4) Heavy lifting
5) Managing people out of the company

6) Reasonable best effort
7) People not living up to their expectations
The dangerous thins is (as least if you have people reporting to you) that you easily fall into the trap of using these words as well, its always the same some people like to seperate themself from others by using words they think the other person has never heard before thus making themself more important or sounding smarter.
Its all bullshit - if you have technicians reporting to you make a note to use their language when you talk to them, don't use managment terms to hide certain aspects of the business - call it as it is - managing somebody out of the company would be one - its finding ways to getting somebody fired.
