Basically “Holding your origin” is to fly in a continuous pattern when the ATC says something like DL1162, hold your origin, airspace is cluttered or DL1162, due to weather, please hold your origin. This is what holding an origin, looks like.
This actually happened yesterday IRL at KJFK, when the weather was terrible yesterday in New York:
Any Blue aircraft, are arrivals. Any Green aircraft, are departures. Any Gray aircraft, are nearby flights.
