I don't know if this one has been spoken of yet, but the term 'Heavy Lift' makes me want to die.
At work it is only ever used just prior to a task being dumped by upper management onto not-upper managment: "Oh, I don't know, Jim. That progress reports sounds like it will be an extremely heavy lift for me right now. Do you think you could handle it?"
This is, of course, followed up by the classic "But, if you're too busy, I guess I can still handle it" immediately followed by a pregnant, expectant pause.
Basically, all business speak drives me insane because it seems to be universally used to only sound smarter than the people around you, or to somehow differentiate yourself: "Our widget development team is really doing a lot of upskilling this year to improve our interdepartmental efficiency."
