I am puzzled why we seem to want to hang another term like 'DC' in front of the words 'square wave'.
I would say by now most practising engineers know what a square wave is when use in context with waveform types.
It doesn't matter whether its superimposed upon a fixed voltage level or not, its still a square wave.
A sine wave signal doesn't have 'AC' in front of the word sinewave.
As Sigmund said, Sometimes a cigar is just a cigar, so lets keep the terminology simple.
