Buzzwords are infectious, like a disease. Use them in a conversation with some of your co-workers, and they’ll be more likely to start using them in their own conversations. And like a disease, they have no real purpose or significance other than to make something worse–in this case, communication.
Buzzwords are buzzwords not because they’re popular, but because they’ve grown to be so overused that their original intended meaning has decayed. They serve as mindless filler words where meaning used to be, and if used with reckless abandon, they can sabotage any hope you had of preserving a productive conversation–especially in an office setting.
