There is an easy way to talk like the friends, or there is a hard way!
The hard way is to watch friends 24/7 for 6 months (which may not be that hard, but it is long). The easy way, well, you've found it, read this guide and you'll have mastered the friends language!
PHOEBE : Â If you want to be Phoebe, the first thing that you have to master is the prununciation. Y should be pronounced 'eee'. Eww should be long, and streached out, so that it is more like 'eeeeewwwwwwwwwww', or make it very shout, and snappy, like 'ew'. Then you have to get the language. You have to add one of these words to at lease every other scentence 'Na-ha', 'Ew' (as pronounced above), 'O' and 'Ok'.
CHANDLER : If you really want to talk like chandler, then you have to add lots of 'not' and 'so', and put the enphasis on them, it works much better when these are both together, 'It is so NOT true'. You also have to change the emphasis on words, for example, 'Could this guide BE much better?' or 'Could that report BE any later?'. You also have to let your thoughts out, and not hold them up, speak your mind! ALSO U HAVE TO FUNNY & MAKE FUN OF YOUR FRIEND SOMETIMES!
Monica : Monica talks rather normally, however you have to add 'Shall We?' in main sentences, even when it is not needed. to answer something , sometimes u have to say "I KNOWWWWW" . You also have to become uptight, and annoyed very easily, and have the ability to say a nice thing with an nasty edge in your voice.
JOEY : If you would like to be Joey, then it is really quite simple. You have to ask all of the really obvious questions, and state the obvious. You also have to not get it when people say things, without saying them.
ROSS : To talk like Ross, you have to add.....long pauses.....and become.....irritated when.....other people......do it. You also have to add high pitched noises, and slightly screw up your face. You also need to pronounce all of your words correctly, and extra bits, in chandlers words 'Oh they do, do they?'!
RACHEL : To be a Rachel, you have to have the ability to start to talk very high pitched when you get upset, and make all of your words end up as a long mumber, so that only you can tell what they mean. You can also start to put a hard sound in your voice when you start to talk nasty!
I hope that that has helped you to learn the basics of the friends language. Look out for the reference book coming soon!
