No , no , no !

There is an increasingly irritating verbal craze for saying certain key words at the end of a sentence twice . These includes Yes ... which becomes yes , yes . Also ive heard " no " being used twice at the end of sentences also today . Worse though is the word " good " becoming " good , good "  Whats going on ? The news reader has just said the word future three times in succession at the end of his sentence just know . I don't get it ? Is everyone retarded . This silly craze is going to get worse before it gets better ...
