That's what koon t'au boe is. The term is usually used in conjunction with a threat, wakakaka.
DAP Seri Delima assemblyperson RSN Rayer had koon t'au boe shown in his face, figuratively, as some violent UMNO people stormed the Penang DUN looking for him, while another pack of hoodlums threatened to burn the DAP building in KL.
Thank the gods (of all denominations) for small mercies as they didn't resort to the deadlier tactics of 13 May 1969, though the threat to burn the DAP building in KL could be considered as a la May 13.
Vision 2020? Unless UMNO leaders like KJ need to get a grip on its members and guide them on more civilised values and behaviour, Malaysia will continue to be a banana ... er ... nation*.
* the usual term is 'banana republic' but I could be charged for lèse-majesté if I use the latter word, wakakaka
If we allow such hooliganism to prevail with impunity, who knows, soon we may join those type of violent people in Thailand who use hand grenades all too easily.
p/s I'm sure you all have enough posts and news articles on Dyana Sofya to read so I have decided to give her sweet self a rest from my blogging wakakaka
