In the days when I was part of a team in a quiz league, it used to annoy me when the "Name for a group of..." questions came up. It was pretty obvious that 90% or more of these collective nouns had been invented specifically to be asked as quiz questions. They even asked for group names for solitary, strongly territorial animals and birds such as cheetas and robins, which will attack any incomer unless it is during a mating ritual. You don't get groups of them, so how can there be a collective noun?

The biggest joke is tha people believe these made up names. In the early 1908s a satirical programme, "Not the 9 O'Clock News" had a sketch where a widlife expert talked about living with a "flange" of gorillas. The term flange was a silly word made up for the sketch. Many years later it has been found in actual scientific papers.

I suggest - A bollox of collective nouns...
Quack!
