What does BLAH mean or stand for ?

BLAH or BLAH BLAH BLAH is extremely popular but is also an extremely stupid acronym to denote “nothing to say”.When we are having a conversation and there is nothing to say or if i dont want to say something i will say “BLAH”.

Its also used to shut someone up online and you feel its not even worth discussing,then i can just say “BLAH” without any other explanation.Its like a retort to something that is dismissive and not worthy of talk.
