Just because someone else used the term doesn't make it right ! There's
plenty of rubbish spouted on the net.

Once in a while someone coins a new term like Heinleins' waldo... but I
don't think its going to happen here.
What has been described is similar to the waveform one would see on the grid
of a class A tube circuit. (but negative voltage of course)
There are a number of waveforms that go in only one direction relative to
ground such as sawtooth waves, square waves, and triangle waves. To refer
to these as say a "DC triangle wave" would be equally confusing without
further qualification.
The closest descriptor that I can think of offhand that might meet with
general acceptance would be "bias signal".
Another waveform that's very similar ( albeit more of a sawtooth waveform rather
than sine wave ) is power line ripple on a DC supply rail.
