Wednesday Blah's Return

From the Merriam-Webster Online Dictionary:

¹blah

Pronunciation:\ˈblä\

Function: noun

Etymology:imitative

Date:1918

1-also blah–blah\-ˌblä\ : silly or pretentious chatter or nonsense
2-plural [perhaps influenced in meaning by blasé] : a feeling of boredom, lethargy, or general dissatisfaction

I propose a third meaning:
