Oh my, yes. And it can be hilarious :)

My wife once worked as a secretary for a recruiter. Just the two of them in a small office. One day I dropped by early to take her to lunch. While I was waiting, I could overhear her boss and a candidate talking in his office. The guy happened to be looking for a job in my own computer field.

They were both babbling nonsense, throwing out terms they plainly did not understand well at all. I could barely stop myself from laughing: two utter posers trying to b.s. each other!
