This is the noise of a sad trombone, usually lowering in pitch after each 'wah,' that sounds off when someone whines or something bad happens. The last 'wah' sometimes is spelled with extra Hs or capitalizations, in order to drag out the last and saddest sounding 'wah.'

Interchangable with a fail, a boo hoo, or finger tear drops.
