QED = Quantum electrodynamics. QCD = Quantum chromodynamics. Is Electroweak Theory = Quantum flavordynamics (QFD)? Why does not anybody use the term "Quantum flavordynamics"? What would a quantum gravity theory be called? "A quantum geometrodynamics" (QGD), perhaps? Is there a separate theory called Quantum magnetodynamics (QMD)? I have seen that term at least in one scientifical journal.
