Capalilly is a term that sorority girls usually call fraternity boys in a degrading sense. The term is used without the knowledge of the person being slandered. Word usage between sorority girls and college age girls about douche bags on campus usually will come down to this word. Its the most degrading term to ever be made for a male. Describing this foul word to another will usually get you into a lot of trouble. Even saying the word capalilly in front of a superior can be grounds for termination.
