n. 1. The degree to which something is bogus. At CMU, bogosity is measured with a bogometer; in a seminar, when a speaker says something bogus, a listener might raise his hand and say "My bogometer just triggered". More extremely, "You just pinned my bogometer" means you just said or did something so outrageously bogus that it is off the scale, pinning the bogometer needle at the highest possible reading (one might also say "You just redlined my bogometer"). The agreed-upon unit of bogosity is the microLenat /mi:k'roh-len'*t/ (uL). The consensus is that this is the largest unit practical for everyday use.
Historical note: The microLenat was invented as a attack against noted Computer Scientist Doug Lenat by a tenured graduate student. Doug had failed the student on an important exam for giving only "AI is bogus" as his answer to the questions. The slur is generally considered unmerited, but it has become a running gag nevertheless. Some of Doug's friends argue that *of course* a microLenat is bogus, since it is only one millionth of a Lenat. Others have suggested that the unit should be redesignated after the grad student, as the microReid.
