The  writer  also  gets  another  reference  from  www.london.allinfo- about.com
. In this article, the writer gets information that when we use this slang in the conversation, we must know when we use the full phrase and when we just
use the last phrase. You  have  to  know,  though,  when  to  use  the  whole  phrase  and  when  to
abbreviate.  Another  example:  Would  you  Adam  and  Eve  it?  I  was  on me Jack Jones when I saw me old china half inching a whistle from the
market.  Well,  I  aint  no  grass  and  hes  borassic,  so  I  kept  me  north  and south shut. Translation:Would you believe it? I was on my own when I
saw  my  old  mate  friend  pinching  stealing  a  suit  from  the  market. Well, Im not a nark informer and hes skint got no money, hard up so
I kept my mouth shut. http:london.allinfo-about.comfeaturesslang.html Sept 1, 2012
B. Review of Related Theories
1. Theory of Rhyming Slang
According to Encyclopedia, the theory of cockney rhyming slang is, Cockney  rhyming  slang  is  an  unique  example  of  a  highly
developed set of codes used by a particular speech community, the Cockneys,  devised  on  the  basis  of  disguise  mechanisms.  It  uses
witty and ingenious coded formulas to refer to objects of affection and
hostility as
well as
taboo topics.

By  this  theory,  reader  can  sum  up  that  cockney  rhyming  slang  is unique and secret language which is used as secret code to communicate in the
members  of  certain  communities.  In  other  words,  cockney  rhyming  slang cannot be used by people outside the community.
According  to  A  Dictionary  of  Cockney  Rhyming  Slang  2010,  the term „cockney‟ definitely meant someone who was born under the sound of
the Bow Bells of St Mary-le-Bow Church in Cheapside,  London, in the road from St. Paul‟s Cathedral. In the past, all of the city of London would have
been within that sound. The first development of rhyming slang started from the late 18
th
century and the early 19
th
century. There are no exact reasons why it  is  started  but  the  most  popular  theories,  that  the  first  development  of  this
language  is  only  for  a  good-humored  joking  by  Cockneys  so  that  outsiders such  as  the  gangs  of  Irish  navies  working  on  canal  and  railway  construction
will not understand. Another theory, Cockney was being used by thieves and criminals to
communicate in public without being understood by outsiders. The last theory is because of the development of this language by an oppressed minority as a
secret language and a defense to give them a bit more inner strength 2010: 3- 4.
2. Theory of Sociolinguistics
In the book An Introduction to Sociolinguistics 1992, Janet Holmes says  that  sociolinguistics  is  a  study  which  deals  with  language  and  society.
Here,  the  using  of  the  language  is  influenced  by  social  factors  and  social dimensions, such as participant, social setting, topic of discussion, function of
the interaction, social distance, status scale, and formality.
According  to  Gumperz  1971,  p.223  in  the  book  An  Introduction  to Sociolinguistics
, sociolinguistics is an attempt to find correlations between social structure  and  linguistic  structure  and  to  observe  any  changes  that  occur.  Social
structure itself may  be  measured by  reference to such factors as social class and educational  background;  we  can  then  try  to  relate  verbal  behavior  and
performance to these factors. The most important thing of sociolinguistics lays on the  role  of  social  dialect  which  is  perform  by  speakers  in  a  certain  area  as  it  is
clearly stated from this quotation : The  bulk  of  sociolinguistic  enquiry  falls  under  the  heading  of
performance,  since  it  deliberately  highlights  the  great  heterogeneity within peoples speech. For example, the differences between speakers
caused by dialectal variation are compounded by variation within the speech of a single person, as with the switch from formal to informal
styles,
according to
the social
context http:www.encyclopedia69.comengdsociolinguisticssociolinguisti

Basically,  the  scope  of  this  study  is  Sociolinguistics.  It  is  the  study  of relationship  between  language  and  society.  It  explains  why  people  speak
differently  in  different  social  contexts.  It  also  identifies  the  social  functions  of language.  In  sociolinguistics,  the  way  people  use  language  in  different  social
contexts can provide huge information about the way language works, as well as about  the  social  relationships  in  a  community.  We  can  also  know  why  men  and
women  talk  differently  and  why  women  tend  to  be  more  related  to  the  word gossip  than  men.  Actually,  in  all  conversations  people  choose  their  words
carefully  according  to  social  factors  and  social  dimensions  or  in  other  words
