Oh, yes we can. In QM we can. Saying "QED" would only determine some
properties of theorie you wanted to refer to, effectively projecting
the statevector (of the meaning you would want to convey) into a
subspace. The meaning of QED would be a linear superposition of two
meanings:

   \Psi = a\Psi_1 + b\Psi_2

This superposition collapses if a "measurement" is done, that is, if
after a period of growing confusion the listener is asking back what
you're talking about and what you mean by QED.

You see, it's all accounted for.
