• mode bit: n. A {flag}, usually in hardware, that selects between two (usually quite different) modes of operation.
  The connotations are different from {flag} bit in that mode bits are mainly written during a boot or set-up phase, are seldom explicitly read, and seldom change over the lifetime of an ordinary program....

• 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....
