秒殺 [miǎo shā] v.
Literally “killed within a second”, this term was borrowed from video games referring to the situation where you are stunned by something ridiculous, embarrassing, and/or unexpected. Sometimes it also means to be defeated by someone instantly.
On the bus, I overheard a 8 or 9-year-old boy telling the little girl next to him, “Who says the future can’t be predicted? At least I know what my child’s surname will be, but you are different. Your child’s surname is still unknown!” That girl replied aloud right off the bat, “Yeah yeah! But my kid will absolutely be my kid, while your kid might not be yours.” Almost everyone on the bus was killed within a second.
