/bif/ To notify someone of incoming mail. From the BSD utility "biff(1)", which was in turn named after a friendly golden Labrador who used to chase frisbees in the halls at UCB while 4.2BSD was in development (it had a well-known habit of barking whenever the mailman came). No relation to BIFF. [Jargon File]
