1. An acronym created by a small, isolated group with the intent of increasing the celerity of text-based communication. Such an acronym suffers from the same problems as and can include workspace jargon. Anacronyms commonly, but not always result from putting two or more of the following types of people in a chatroom: computer programmers, MMORPG players (case in point), pre-pubescent females, GI's, and/or slow typists.

The irony of such an acronym demonstrates itself because of the acronym's tendency towards the specific and arcane. Namely, an individual desensitized to the use of the acronym (not exceedingly dissimilar to the individual who no longer notices his/her own swearing) will attempt to use the acronym in a textual conversation with an individual not familiar with the group of individuals or the acronym in question. This invariably leads to a message of one or more marks of interrogative punctuation by the uninformed party. Taking the time to explain the meaning of the letter sequence, the informed party defeats the intended purpose of the acronym by possibly increasing the length of text sent by upwards of four lines.

2. A usually nonverbalized acronym which has been verbalized. This is considered a taboo in most situations. The individuals to whom the offending party has "anacronyzed" will most likely look incredulously at the offender.

3. A completely unnecessary acronym. Almost every acronym in this third definition pertains to the first definition.

4. A misused acronym.
