My poor (new) friend Barnze. Oh my gosh, his Rogan Josh has gone right through like Vindaloo. Or something.
Owing to his defiantly punk status (and photo) I think I shall only ever refer to him in glowing terms and delicate phrases; dear boy.
Just to pee him off, you understand.
That said, courtesy of this nice young man (muahaha) I present you with THIS LINK to a page full of collective nouns.
I like (but would question) many of the ones relating to groups of people, ones such as:
A conjunction of grammarians
A worship of writers
A curse of painters (illusion, misbelieving)
Still, an obstruction of dons and an ambush of widows do rather fit my sense of humour.
