Cause people say wire A or wire B is ground....

Rememer that there are several *different* ways of using
the word "ground". Don't assume that they all mean the
same thing. Many words in English (and likely other
languages also) have several different meanings. We
must determine which meaning is appropriate or we
will be confused.

I felt that my above description did not meet the requirements of
circuit is why I am confused.

Any connection that conveys a signal/power from one
point to another is a "circuit".

Generator.A - transformer - "earth" - Generator.B

One terminal of the generator is connected to a ground rod.
The other terminal is connected to a wire that travels many
miles across countless power poles to the transformer which
supplies your home. That wire connects to the primary of the
transformer. The other side of the primary conects to ground
at the base of the pole.

The current starts at the generator, travels many miles over
the power pole wires, connects to the transformer outside
your house, then then current travels back many miles through
the crust of the earth to the generator completing the "circuit".
A "circuit" is a circular path. I urge you AGAIN to read all the
dictionary definitions of the word "circuit".

is an mspaint "schematic" of what I think when I hear "ground" in an
AC
circuit.

1. is that how an rca plug looks when connected in the real world?

For the purposes of your discussion, yes.

2. if so, where is the groudn going (to the chassis?)

Your ground symbol is shown connected to one "node"
of your circuit. The circuit would work just as well if
it were not there.

Don't really know what you mean by "where is it going"?
Your circuit would be complete and operational without
your "ground" connection. Where is *what* going?


..how can a negative voltage mean a specific signal flows from
common
ground - left/right conductor if each channel has differing values at
each
points? Or is it more of a "pulling" in electrons than a "pushing"
electrons?
e.g., when the flow is from common ground - channel, it's pulling in
X or Y
volts, but when flow is from signal-common ground, it's pushing out X
or Y
volts? If the push/pull analogy works, I think I understand.

Take the circuit you drew. Now make a mirror image
of it and connect the two "grounds" together. That is
what you have with a stereo mini-jack. Each circuit
(the left circuit and the right circuit) is a complete
path in itself and doesn't care what the other one is
doing or whether it is connected to it or not. Follow
the current flow around the "circuit".

Just as you can take your original diagram and either
connect the ground point to the earth, or not. The
circuit doesn't care because the current is flowing
through the circular path (the "circuit") and is complete
in itself.

The common node of the stereo mini-phone connector
(the "sleeve") carries the return current for BOTH the
left channel "circuit" and the right channel "circuit".
