Simply, "speaking in, or the language of, acronyms", including the abbreviated jargon of the particular subculture in which the acronymns develop. This results in different kinds of acronese, just
like there are different languages. There are also unspoken rules of form in each subculture. So, in the IT
world, TLA is a "Three Letter Acronym", but FLA is not a "Four Letter Acronym". That is too obvious, and would violate the unspoken rule that IT
people are to look down and intimidate all other lesser mortals as inferior beings. So, XTLA is the
proper form, an "Extended Three Letter Acronymn".
In computing acronese, the "IT Ten T" translates as "Moronic User Error". It is written as "ID10T!"
In the early acronese of letter-writing,
LOL meant "lots of
love". In acronese of social text messaging, it means "Laugh out Loud!" PIMP LOL means, "Pee in my
pants laughing out loud!"
