In Top Gun (1986), a flight got hit by a missile:
Pilot: I'm hit! I'm hit! We're coming apart! I can't control it! Hold on! Zero for twenty! We're going down!
What does "Zero for twenty" mean?
The line said in the movie is "090 for 20", and he is calling out his relative position.
It is in a standard format for a range and bearing callout, with the 090 being magnetic bearing and 20 being nautical miles.
The clip is too short for the context, but range and bearing could be from the ship, from an arbitrary pre-briefed "bullseye" location, or from the engaging fighter itself.
SHIP: If they were using the ship as a reference point a quick check of the TACAN is all that's needed. In this case the tail of the needle, or radial, would be at 090 and DME would read 20. A combat engagement 20 NM from the ship is VERY close, so they were probably using...
BULLSEYE: In the more likely event that the ship is controlling electronic emissions and the TACAN is off, a mission cycle will assign an arbitrary Latitude/Longitude as "bullseye". This bullseye point then becomes the center of an imaginary VORTAC in the middle of the ocean. All aircraft on that mission cycle will enter this location in their navigation systems and reference their position off it as if it were a real navaid.
In this case the hit pilot is obviously calling out his position relative to whatever anchor point they have chosen to use as a reference on this mission to get help on the way.
If, (in the case of the last example) the transmission were coming instead from a tactical controller onboard the ship or from AWACS, the call would be for the engaging fighter to help get their radar on the target. For example, "Maverick, bandit at your 090 for 20."
