Explain a Confusing Piece of Office Jargon in Plain Terms

Someone said a phrase in the meeting and you nodded along, having no idea what it meant. This gives you the plain definition, an example of it in use, and why people bother with the jargon at all. No judgement, just an answer.

Explain what "{JARGON_TERM}" actually means in a workplace context, as if to someone new to the industry. Give a one sentence plain English definition, then one realistic example of it being used in a sentence, and one sentence on why people use the jargon instead of plain language. Keep the whole answer under 80 words, no waffle.
