I don't know about "That's a warp." Do you mean "That's a wrap"? "That's a wrap" is an old expression from the movie industry. When all the filming was finished was finished, the movie director would say "That's a wrap!" I'm not sure why they said that, but it must have meant that it was time to clean up and go home, or that it was time to take the film footage to the editing room. So you can say "That's a wrap" or "Okay everybody, that's a wrap" when you've all been involved in some project and the work is finished, so it's time to clean up and go.
