I wish I could describe Singlish as well as solios described Pittsburghese:

That’s Pittsburghese for you, though – this town will stop loving football long before it embraces the hard consonant. A lot of the locals, when they speak… sentences do not emerge. What comes out is a pile of loosely related vowels, punctuated with the occasional grunt and the glimmer of realization in their eyes that they’re not getting through to you. It’s not for a lack of trying – the inhabitants of the region all seem to have evolved some sort of highly specialized section of larynx – a post-larynx, perhaps – a section that belt-sands all of the hard pointy bits of words clean off, leaving only the most basic impression of phonetic intent.
