Line Up and Wait
But I don't recall EVER using Angels for altitude. But did do the XX point X call. Again, not proper from AIM, but controllers seem to understand.
No, I never used Angels for altitude, either, but I do remember hearing on Guard in Vietnam, "Bandits! Bandits! Angels seven, southbound" (and a reference to a fix I have forgotten). We were flying from DaNang to NKP across Laos and the thought of being jumped by a flight of MiGs was unsettling. However, the North Vietnamese fighters did not venture as far south as we were. At 7,000 feet they were lower than us, but in a C-130 that's not necessarily a good thing. Our only defense would be to get down very low above the jungle where we could hope our camouflage would make it hard for them to see us, and then to try to slow down and turn inside of them. The flight deck was very quiet until they turned away from the border and headed back north.
