handle

[from CB slang] n. An electronic pseudonym; a `nom de guerre' intended to conceal the user's true identity. Network and BBS handles function as the same sort of simultaneous concealment and display one finds on Citizen's Band radio, from which the term was adopted. Use of grandiose handles is characteristic of crackers, weenies, spods, and other lower forms of network life; true hackers travel on their own reputations rather than invented legendry.
