Today's Word of the Day means...
[Unix] 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 to support "rogue(6)" and has since become one of Unix's most important and heavily used application libraries. Nethack, Omega, Larn, and an entire subgenre of computer dungeon games all took off from the inspiration provided by "rogue(6)". See also nethack.
