Apronyms for Mac

From Cocoa:

Apronyms allows you to view the apronyms from the Apronyms web site (http://apronyms.com) without staying on the internet. You can view the apronyms in their plain alphabetic listings, by category, or using the very flexible search facility. You can also add your own apronyms, and optionally submit them to the web site. If you need help creating an apronym, the apronymising tips, submission guidelines and Acronyms Forums are only a menu item away. At any time you can download new and updated apronyms from the site without losing your own additions.
