snail mail
     
         or "snailmail", "smail" from "us mail" via
        "usnail"; "paper mail".  bits of dead tree sent via the
        postal service as opposed to electronic mail.  one's postal
        address is, correspondingly, a "snail mail address".  there
        have even been parody usnail posters and stamps made.
     
        the variant "paper-net" is a hackish way of referring to the
        postal service, comparing it to a very slow, low-reliability
        network.  sig blocks sometimes include a "paper-net:"
        header just before the sender's postal address; common
        variants of this are "papernet" and "p-net".  note that the
        standard netiquette guidelines discourage this practice as a
        waste of bandwidth, since netters are quite unlikely to
        casually use postal addresses and if they really wanted your
        snail mail address they could always ask for it by e-mail.
     
        compare voice-net, sneakernet, p-mail.
