1. n. (Also `leecher'.) Among BBS types, crackers and warez d00dz, one who consumes knowledge without generating new software, cracks, or techniques. BBS culture specifically defines a leech as someone who downloads files with few or no uploads in return, and who does not contribute to the message section. Cracker culture extends this definition to someone (a lamer, usually) who constantly presses informed sources for information and/or assistance, but has nothing to contribute. 2. v. [common, Toronto area] To instantly fetch a file (other than a mail attachment) whether by FTP or IRC file req or any other method. Seems to be a holdover from the early 1990s when Toronto had a very active BBS and warez scene.
