What is Vomit Blood?
Strange way of expressing disgust or doing something reasonably bad. Usually used by strange Singaporeans who have nothing better to do.
Singaporean: Wah siao, when i went to NS, i had to learn how to use a pistol. The noise so loud. I so scared. Can vomit blood liao.
To be extremely pained, stressed and frustrated from a situation. Use is synonymous with "pop a vessel".
He was so unbelievably stupid that arguing with him caused me to vomit blood.
