It's unfortunate that despite all his accomplishments, Dr. Chua's lasting legacy may be the creation of a new euphemism - personal friend.
Since this concept of "personal friend" may be new to some Malaysians, I would like to point everyone to the casual relationship section in Wikipedia (warning: has some rude words).
A friend opined that "personal friend" sounds like an oxymoron, but I disagreed, because the two words are not contradictory. "Personal friend" would be a type of redundancy, or more accurately, a pleonasm (the use of more words than necessary to express an idea clearly).
Now he may have questionable morals (and grammar), but I still think the formerly honourable minister should have gone out with a bang.
Instead of the initial "I will not resign" statement, he should have reenacted that famous scene from Gladiator, and snarled at everyone:
"Are you not entertained?! Is this not why you are here?!"
