In this regard, is Blah a real word?
Blah is defined as a word to use when a person doesn't know what to say or doesn't want to use all the words needed to complete a sentence. An example of blah is what a person says at the end of a long list of items instead of actually listing the items, "She had a coffee, doughnut, blah, blah, blah."
Blah, as suggested by the Wiktionary has an uncertain origin: Sense “Idle, meaningless talk” (1940), probably imitative or echoic in origin. Perhaps, but cf Greek "barbarbar” 'unintelligible sounds' (Grillo 1989:174). Also may be connected with bleat.
