That message communicates three things at once:
- They’re working

Short. Efficient. Context-heavy.

TDY did not start as internet slang.
It comes from military and government language, especially in the United States.
Where TDY actually comes from

- Refers to official travel orders for a limited period
- Different from permanent relocation or deployment

How it moved into texting
As service members, contractors, and government employees began texting casually, TDY slipped into everyday messages.
Over time:

- It entered casual texts without explanation
That’s how formal language turns casual. Slowly. Naturally.
