B1FF meaning and definition

Fictitious USENET poster, created as a joke circa 1988 supposedly intended to show the USENET community how NOT to communicate with the world. Parodies usage of teenagers, "n00bs," and others not familiar with netiquette. Typical language includes all caps, intentional misspellings and number substitutions, exclamation points, quick flames and long signature files. BIFF posts articles using his elder brother's VIC-20. BIFF's location is a mystery, as his articles appear to come from a variety of sites. However, BITNET seems to be the most frequent origin. It is believed that BIFF was originally created by Joe Talmadge <jat@cup.hp.com>, also the author of the infamous and much-plagiarized "Flamer's Bible". The BIFF filter he alledgedly wrote is said to have been later passed to Richard Sexton, who posted BIFFisms much more widely.
