(1) When I was a kid
You select one alphabet you like, then break up your words into syllables, and insert the selected alphabet and an appropriate vowel in between the syllables. Complicated? Demo... demo...
Say you select the alphabet M and wanna say the word "suka".
SUKA --> su + ka --> su + mu + ka + ma ==> SUMUKAMA
If the original word ends with a consonant, just carry the consonant right to the end, after the last insertion.
SUKAN --> su + ka + n --> su + mu + ka + ma + n ==> SUMUKAMAN
Sakayaka sukukaka hakatiki sekebakab Akadiekijikin nakak bekelakanjaka sakayaka mikinukum kokopiki.
The kids then loved to use the alphabet F, and they called the codespeak 'the F Language'. Me, I preferred the alphabet K, easier to spew forth without potentially spraying saliva on my friends hahaha :-)
(2) Then there was the 'Bahasa Terbalik'. Surprisingly, my mom is very adept at this! However, it can only be used with two syllable words. You simply take a word, break it up into syllables, rearrange the order of the consonant but not the vowel. Ahh... demo... demo...
LABU --> la + bu --> l + a + b +u --> b + a + l + u ==> BALU
However if the syllable has three alphabets or the word ends with a consonant, then the consonant stays at its place.
PERGI --> per + gi --> pe + r + gi --> ge + r + pi ==> GERPI
RUMAH --> ru + mah --> ru + ma + h --> mu + ra + h ==> MURAH
Actually there's not really a strict formula, its more like sesedap rasa :-)
(3) Next is the very exaggerated 'Bahasa Niknong' which only two people I know who can speak it fluently, namely me and my best buddy Jamie. That's because we concocted it ourselves in Form Two hehehe :-)
As in the earlier mentioned codes, the words are broken into syllables, but only the last syllable is changed. Turn the last vowel in the last syllable into 'ik', then duplicate and insert the last consonant from the last syllable, and lastly add in 'ong'. Hehe... demo... demo....
APA --> a + pa --> a + p (-a) + ik + p + ong ==> APIKPONG
If the word ends with a consonant, the consonant is sometimes dropped.
LEMAK --> le + mak --> le + ma (-k) --> le + m (-a) + ik + m + ong ==> LEMIKMONG
But sometimes the last consonant isn't dropped.
BASIKAL --> ba + si + kal --> ba + si + ka + l + ik + l + ong ==> BASIKALIKLONG
This one is quite hard to understand, coz different words may end up sounding similar, so you have to know the context of the word in the whole sentence. For example, the words 'ada' and 'adik' both end up as 'adikdong'. As a sentence, it's nonsensical and sounds practically insane for the uninitiated hehehe :-)
Awikwong sudikdong makikkong kikkong? Perikrong sayikyong lapikpong liklong, jomikmomg pekeniknong rotiktong caniknong samikmong tiktong tarikrong!
(4) OK last one is 'Bahas Separ' which is actually 'bahasa separuh' but even it's name has been trimmed hehehe :-) Me and buddies used this alot in the early 1990s, waaaayyyyy before it became favoured among our silembut friends. Unfortunately there's no registered copyright on stuff like this, otherwise we might have gotten at least a little recognition for it :-P
Again, break the word into syllables. Then maintain the consonant of the last syllable and omit the vowel. Throw in an occassional alphabet S at the end of some of the words in your sentence, just for kicks. Voila! Your new word is about 40% shorter, good economics, eh? Demo.... demo.....
Bagi dia buah limau yang kecik tu ==> BAG DI BUAH LIMS YANG KEC TU
Oh yeah, single syllable words are maintained, as they can't possibly be made any shorter :-) And some common words which couldn't be so coded, are replaced totally with another word, for example, the word 'tak' is replaced with 'dinch' which is a twisted variation of the English word 'don't', used to indicate anything negative.
OK DAH, DINCH AD AP-AP CERITS LAG LAH
Please feel free to knock your head on the wall, I heard it can overcome headaches people get from reading garbage postings.... hehehe :-D
