What does ACA stand for?
'aca' or 'ACA' could be any number of a cappella related things (or things outside the community as well.) Within the community:
'Aca' - colloquial term for a member of the contemporary a cappella community
'aca' - shorthand for 'a cappella', used primarily within the a cappella community, hence
'aca-' - prefix used to associate whatever comes after it with a focus on a cappella music (e.g. acageeks are 'a cappella geeks.') This prefix is also featured prevalently in the film Pitch Perfect as a generic addition to normal words/phrases (e.g. “Aca-scuse me?” as a means of creating a cappella portmanteus and slang. This was not nearly as common within the real-world until the film came out.
ACA - acroynm for the A Cappella Community Awards, organized and given out (usually) every year by the Contemporary A Cappella Society (CASA), often referred to as the “People’s Choice” of a cappella (the CARAs (Contemporary A Cappella Awards) are known as the “Grammys” of a cappella)
Hope this answers your question, aca-nonymous!
