A Spangle of Cheerleaders

I've always been fascinated by the poetic names we give groups of animals. Terms like a School of Fish or a Herd of Cattle are pretty common, but what about a Murder of Crows? Or a Parliament of Owls? A Shrewdness of Apes?

The attachment of Shrewdness or Murder seems random, but somehow conveys a familiar quality to whatever species it describes. A Sugar of Crows or a Dalliance of Apes doesn't feel right.

Why don't we classify humans in this way - by job, or age, or social placement? I've taken the liberty of making up a few.

A Cosine of Architects
A Fickle of Actors
A Pod of Douchebags
A Thrall of Gamers
A Tyranny of Eighth Graders
A Straggle of Senators
A Fidget of Toddlers
A Crime of Lawyers
A Fuss of Bridesmaids
A Fetor of Paparazzi
A Squall Day Traders
A Canister of Garbage Men
A Guile of Advertisers
A Stew of Psychiatrists
A Thicket of Priests
A Crush of Teachers
