That is the title for the essay I am writing for New Malaysian Essays 1. The subtitle (!) is 100 Word Meanings that Cannot be Found in the 2007 Edition of Kamus Dewan. You will be surprised that even 'rempit', in the manner now used by us, is not in that dictionary.
Most of the words will be found here. Needless to say I will need to cross-check with Kamus Dewan to make sure the words are NOT there. I will be happy to email the essay to you if you wish to peruse it – especially if you happen to know some slang terms I do not. Just contact me :-)
The title 'Unwelcome Words' is a homage to an epistolary story by one of my favourite writers, Paul Bowles. Reading it as a teen, I was so excited that it mentioned Kuala Lumpur! So now Kuala Lumpur is writing back, as it were.
