BnF
Back and Forth - the daily email loop between a small group of close friends. Typically about nothing. Usually consumes more than an hour or 2 combined. During work hours. Can result in arguments about meaningless topics.
Today's BnF is unreal. I have not done a thing at work except read all these rants on the housing market, golf, NFL, marketing and Michael Irvin.

Stands for "big name fan", as known on tumblr. Within a fandom, there are usually multiple people who are known fandom-wide and who have many more followers than other people. These people are known as "BNF"s.
Evarren was a BNF from klaine fandom before she deleted her blog.
