Realistically how many random people other than you know that. I’m not unfortunately hanging around Nobel Prize Laureate's. I bet if they get slammed with a “vacuous jibberish” that would give them reason to pause. Around 7:00 PM tonight the first person that introduces a topic better duck.As compared to non-vacuous jibberish? You see, it's either jibberish or it is not. 'Vacuous' is assumed when it comes to jibberish. Therefore, the phrase 'vacuous jibberish' is redundant.
