I think there have been a few threads here about awful business slang (reaching out, blue sky thinking, etc), but I found myself saying something that I'd never ever say at home.
I was talking in a meeting where nothing was really agreed, and it was all a bit "blah blah", and I described it as a "rich discussion".
I notice that I talk about "leveraging" finance, asking about the "envelope" of the financing, and even talking about "bilateral" meetings.
While this language is not quite clichéd, they're well understood terms at work, but I'd never (fingers crossed) use them at home or in the pub.
Do you use similar phrases that you'd admit to using at work, but never outside?
