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.
