我是孩儿他爹我是孩儿他娘
[wŏ shì hái ér tā diē wŏ shì hái ér tā niáng]
The nickname 'I am the Father, I am the Mother' is quite amusing and ironic. It implies that the person has many roles to play or takes on the responsibilities of both parents in life, juggling various aspects of parenting with pride and humor.
