It's an inside joke that I plan to make a webcomic out of one day.
This is where it started.
The story behind CA is that while Chrono Trigger was released at the tail end of the SNES's life, Chrono Alcoholism was released five years after it was dead. Only six copies were made, and they were accidently shipped to a clothing store in Utah. It is noncanonical, and included Chrono Cross characters, but it assumes the CC story never happened. (Although several of the characters play Chrono Cross at one point in the game).
The main character is named Alco Hall, and he and his best friend Alma Norman try to find the secret town of Booyaville, repeal a strict prohibition that was instilled upon Zenan, and rescue Crono from the authorities. The story takes place, of course, in the Chrono Trigger universe, and time travel is possible. There are exactly 356,787 playable characters, and many cameos from other games and universes as well.
This is the box art of the game:
