This reminds me of colleague who was definitely a "word of the week" kind of person.
One week, his favourite word was "dovetail".
"It is important that for us to be a solid, dependable and effective supplier that we can dutifully dovetail our services to match the requirements of our customers."
.. but of course, how could I ever have thought otherwise
If it had stopped there fine but it did not. Later on, we were talking about football and I asked why a manager might substitute a striker for defender or the other way around instead of just like for like.
Guess what.
"Sometimes it is necessary to change the structure of the team on the park but then the new player has to be able to dovetail into the structure that is already there apart from the player being replaced."
I doubt you could talk to him about the weather, or anything else, without him using his word of the week.
