This tag has been burninated! If you notice it re-appearing with some frequency, please propose that it be blacklisted.

friendship seems like it's highly unnecessary on Stack Overflow, it has 113 Questions (where none of them are improved by the tag) and no tag Wiki.

According to the Burnination-Request rules - criteria #2 I request this tag to be deleted from SO because it is blatantly off topic on the site.

We should probably kill it with fire.

For friend classes in object oriented programming, the friend can be used, already exists, and has a tag wiki.

Answers about these specific classes will then have to be re-tagged.

I came across this tag because of this blatantly off topic question by the way, and I was surprised by "There is a tag for that?!"
