I agree with the ArchAngel Angela.
As a basic series of ground rules:
: Acronyms 'ought' to be real words, or at least common usage of non-words,
: Expansions 'ought' to made of real words,
: Acronyms 'ought' to be more than one letter long
sub-rules
: Acronyms should be spelt correctly whenever possible
: misspellings are permitted in the expansion if it improves the fun/sense/explanation/aptness of the acronym
: modifying existing acronyms is not 'really' acceptable.... "AA", "CIA" etc... if all you are doing is playing with the original words. (e.g in view of the series of spies uncovered, one could posit that CIA = Communist Intelligence Agency, but it wouldn't really be creative.
A propos of the Alcoholics Acronymize: those two words - in any combination - are the personal property of Tony! (see the stack for details). :-)
The ZZZ and ZZZZ should really not be in the stack.... nor should the ZZZZZZZZZZZZMT.
