你像胃病时不时疼的要命
[nĭ xiàng wèi bìng shí bù shí téng de yào mìng]
'你像胃病时不时疼的要命' can be explained as 'You are like a stomachache that hurts like crazy once in a while'. It uses metaphor of physical pain coming out unpredictably to illustrate a person whose appearance, actions or words cause emotional turmoil periodically.
