Definition

A gloriously meaningless placeholder word that simultaneously means everything and nothing, deployed when your brain has completely abandoned the search for the actual word you need. It's the verbal equivalent of a shrug emoji, perfect for filling conversational voids when coherence is optional.

Example Usage

I was trying to explain the plot of that movie but my mind went blank and I just said 'and then the sner happened' like that explained anything.
