Common code or jargon for copying someone else's work and claiming it as your own.
Frequently used in the military, even for the most mundane of tasks.
Especially applicable when the search to copy someone else's work requires more work than actually doing the work yourself.
1. If you've already done the work, there's no need to reinvent the wheel, just send me a copy of yours.
2. I'm sure I could do this, but why should I, there's no need to reinvent the wheel.
3. Whenever you copy and paste a request, remember to include that you don't want to reinvent the wheel.
