你爹有喜了你娘怀孕了
[nĭ diē yŏu xĭ le nĭ niáng huái yùn le]
The name directly translates into 'Your dad has good news, your mom is pregnant'. In the past centuries, the phrase could mean both genders are joyful about having or expecting a baby but now this kind of expression would generally be deemed vulgar.
