frogging [University of Waterloo] 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 terminak for a historical example and compare
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.
