I have already been a strong proponent of more interesting collective nouns for nationalities, but I do not think we should stop there. We also need it for professions.

We could have a corruption of politicians, a gangbang of prostitutes, a nepotism of businessmen, a vacation of public servants, an overcharging of consultants, a bad touch of Hollywood actors, a calendar of runway models, a coke trip of doctors or traders, a complaint of school teachers or a coffee break of contractors.
