我长了一副未来你爸的模样我生了一张未来你妈的脸蛋
[wŏ zhăng le yī fù wèi lái nĭ bà de mó yàng wŏ shēng le yī zhāng wèi lái nĭ mā de liăn dàn]
Humorously this name implies that the person could resemble future family members. It's a lighthearted way to imagine how their relationship might lead to children who look similar to both partners.
