group of assholes 

There is no universal term for a collection of assholes in one place, instead terminology tends to cross religious and social economic boundaries. In the North of England one might encounter a Pile of assholes at a soccer match, whereas in Detroit this same group would be a Pack. Some particularly unflattering examples exist, such as the Nasty Bag of assholes (South East Asia).
