The Jargon File (version 4.4.7, 29 Dec 2003):

rogue


    1. [Unix] n. A Dungeons-and-Dragons-like game using character graphics,
    written under BSD Unix and subsequently ported to other Unix systems. The
    original BSD curses(3) screen-handling package was hacked together by Ken
    Arnold primarily to support games, and the development of rogue(6)
    popularized its use; it has since become one of Unix's most important and
    heavily used application libraries. Nethack, Omega, Larn, Angband, and an
    entire subgenre of computer dungeon games (all known as ?roguelikes?) all
    took off from the inspiration provided by rogue(6); the popular Windows
    game Diablo, though graphics-intensive, has very similar play logic. See
    also nethack, moria, Angband.

    2. [Usenet] adj. An ISP which permits net abuse (usually in the form of 
    spamming) by its customers, or which itself engages in such activities.
    Rogue ISPs are sometimes subject to IDPs or UDPs. Sometimes
    deliberately misspelled as ?rouge?.

Bouvier's Law Dictionary, Revised 6th Ed (1856):

ROGUE. A French word, which in that language signifies proud, arrogant. In
some of the ancient English statutes it means an idle, sturdy beggar, which
is its meaning in law. Rogues are usually punished as vagrants. Although the
word rogue is a word of reproach, yet to charge one as a rogue is not
actionable.  5 Binn. 219. See 2 Dev. 162 Hardin, 529.
