Blah

Blah is the perfect word/sound to describe an indescribable mood. It has emerged in such a blah year (2020) and the word is fairly versatile.
It lightens up any serious situation and usage of the word has become ubiquitous in Christchurch, New Zealand.

OMG I'm going back into lockdown because of the covid-19 pandemic! Blahhh!
Kidney stones? Blah
Oh your BF cheated on you? Well Blahhh
