一夜激情当了爹一夜激情当了妈
[yī yè jī qíng dāng le diē yī yè jī qíng dāng le mā]
In Chinese culture, this phrase implies 'A Night's Passion Led to Parenthood'. It refers very colloquially to a one-night encounter resulting unexpectedly in having a baby. The tone can come across as light-hearted while discussing sensitive subject matter such as out-of-wedlock births and single parenthood.
