Wikipedia:WTF? OMG! TMD TLA. ARG!
or: What The Fuck? Oh My God! Too Many Damn Three Letter Acronyms. ARRRGGGHHH!!!!~!@!~1`2
Basically, when WP:EDIANS WP:CITE pages in the WP:PRJ WP:NS, they often refer to them using WP:CUTS like "WP:BEANS", "WP:BALLS", and "WP:FU". While these WP:ABB are great for WP:RDR to WP:A particular page you WP:USE often, it's probably a WP:BAD idea to make a WP:POINT of using these WP:TLAs in daily WP:TALK, lest your discussion ends WP:UP as WP:NONSENSE like the WP:TITLE of this page.
Translation
Basically, when Wikipedians refer to pages in the Wikipedia namespace, people often refer to them using shortcuts like "WP:BEANS", "WP:BALLS", and "WP:FU". While these abbreviations are great for quickly getting to a particular page you use often, it's probably a bad idea to make a point of using the three letter acronyms in daily conversation, lest your discussion ends up as nonsense like the title of this page.
Moral of the story
Always use a proper name for a Wikipedia namespace page when discussing it. If you find you are getting sore wrists and fingers from all the typing, try to simplify or summarise the pages you are referring to, so that in future you only need to refer to a single link. ;-)
