你信誓旦旦说的承诺是狗屁
[nĭ xìn shì dàn dàn shuō de chéng nuò shì gŏu pì]
This name implies the speaker's deep disillusionment or cynicism. In a context of someone feeling betrayed or disappointed, 'the promises you made with such confidence are BS' suggests that words and assurances previously given by someone else are seen as worthless.
