Buzzwords
"We'd like to discuss possible synergies with you..."
All this does is flag you as someone that doesn't actually know big words, but instead read the buzzword manual in an attempt to sound intelligent. 
No Hoff. If someone says
"We'd like to discuss possible synergies with you..."
It means get ready to find a new job. You are the synergy and you about to be synergised right out the door.
My least favorite "corporate" speak when people say they are going to "setup a cadence of meetings". NO! NO! What you are going to do is setup a reoccurring meeting. Stop misusing words!
Haha, that's a great one. I love when people take a phrase that is perfect for the situation and butcher it just to use "different" words.
And nah, this was a call from a potential vendor that was trying to do business with us, so I'm not concerned.

In government it's **** like "preparing documents at a 'high level'" or "give them a 'high level' overview" which actually means "lower level" or "dumbed down and stripped of any details and/or contextual information that is relevant to fully understanding the subject.
In that usage, "high" isn't used to describe the level of detail, it's more like saying "stratospheric" (high in the air). You describe the macro happenings of the situation, but not the low-level nitty-gritty details. It's always seemed a bit counter-intuitive to me, and even more so is dependent on what the speaker really means to say vs what they say.
