south
When used as a noun to refer to a specific region (like "the South" in the US), it is usually capitalized. As an adverb, it describes direction and does not require a preposition like "to" or "towards," though those can be added for emphasis.

🎬Tuesday afternoon; Victoria is in a board meeting while David is pretending to work from home.
Victoria
The Q3 projections are going south. Where are you?
David
Just circling back on some deliverables now. Be right in.

Victoria uses the idiom 'go south', meaning to deteriorate or decline rapidly, to describe the failing projections. David responds with corporate buzzwords ('circling back', 'deliverables') to mask his absence and anxiety.
