When working for an Fortune 500 Aerospace Co. many years ago, we had a Secretary who was finally promoted to Technician due to her incompetence (and to avoid terminating a single parent). The "Peter Principle" was in effect and it was a mess! (She was eventually terminated.)
As a Technician, she functioned much better doing routine manual-type things. She tried, but couldn't cut it even as a Tech. Complaints were constant and she redid more than she accomplished. But she loved to throw in big words when talking with men in an attempt to impress. Often she had no idea how to use the word (or what it meant). None of this mattered to her. She was too busy looking for Mr. Right!
My office was across the hall from the cubicle she and several other employees sat in and their voices drifted in my open door throughout the day. One day I heard her say, "It's pneumatic." Followed by a long pause. Then: "It's a scientific word. (pause) No, it's not in the dictionery. (pause) "Just like it sounds: n-u-m-a-t-i-c ." 
By then, another manager had heard her latest "brilliant lesson to the world" and we both left our offices bursting with laughter. 
Apparently whomever she was talking with on the phone had backed her into a corner!!! I have no idea how she ended the call. We were laughing too hard to care. Neither of us told her as we headed for the coffee machine, grateful neither of us had her to supervise! I have no idea if her supervisor was in his office or not.
That's how 50% of her conversations went. Listening to her was frustrating. I tried the first few years, but nope; couldn't interact with her and keep my sanity. Nice person, but used pot & drugs; it was telling the next day; she wasn't very bright or awake the following day(s)!
Words and behaviors count in the workplace.
Money screams; wealth whispers.
