Deletion
First of all, in this sense it's a noun, not an adjective. Secondly, you say "normal definition", but what you mean is "normal to a Briton'. Americans never use friendly as a noun. This page, and really most of the pages in category:cricket, exist because an awful lot of DW fans aren't British, and won't be familiar with the term. Thirdly, this term is now pretty well linked, and its removal would require some work.
Some of the pages that we create on this wiki are done to help non-Britons understand specialised British jargon, and that's a good thing.
