While not uniquely $in-gaporean, it is typically $in-gaporean.
Verbal abuse is everyday language in $in-gapore. We Chinese call it "stinking mouth" - I call it "dog's breath".
My beloved Hong Kong gals, stay away from the $in-gaporeans if you do not want to experience what's typically $in-gaporean. Come to me now. *Hugs*
