On reading that a number of priests had gathered for a CONCELEBRATION of the Mass, it seemed that a formula had presented itself for the generation of collective verbs which might be used in the manner of the spate of collective nouns with which we have become familiar. James Lipton's "An Exaltation of Larks" (Grossman Publishers, 1968; paperback edition Penguin Books, 1977) sets forth large numbers of legitimate collective nouns and adds many new coinages, from a colony of bacteriologists to a cc of Mexicans.
