frogging
 v.

    1. Partial corruption of a text file or input stream by some bug or
    consistent glitch, as opposed to random events like line noise or media
    failures. Might occur, for example, if one bit of each incoming character
    on a tty were stuck, so that some characters were correct and others were
    not. See dread high-bit disease.

    2. By extension, accidental display of text in a mode where the output
    device emits special symbols or mnemonics rather than conventional ASCII.
    This often happens, for example, when using a terminal or comm program on a
    device like an IBM PC with a special ?high-half? character set and with the
    bit-parity assumption wrong. A hacker sufficiently familiar with ASCII bit
    patterns might be able to read the display anyway.
