Pride of Rhinos

Canadian English - collective noun
Canada has indigenous rhinoceros, that although rare, are increasing in number and presently have been spotted in all Canadian provinces and territories.
On rare occasions when two or more Rhinos gather, the group is refered to in Canada as a pride of Rhinos. It is not clear if the term pride was attributed to them because of their pride in being Canadians or because when they gather they have such a "damm good gay time". Prides of Rhinos are often active in the month of June as they celebrate the arrival of summer by joining in pride parades.
Alternatively they are also referred to as a party. A party of Rhinos is commonly a pride of Rhinos planning how they can have fun when a federal election is called.

The pride of Rhinos gathered for a beer until someone yelled, "an election has been called", the gathering then became a party.
