我的笑如此歇斯底里我的傲如此不可一世
[wŏ de xiào rú cĭ xiē sī dĭ lĭ wŏ de ào rú cĭ bù kĕ yī shì]
'My laughter is so hysterical, my pride so unprecedented'. It implies that the person has extreme emotional reactions and an attitude that seems overbearing/arrogant to others but is a coping mechanism for deeper emotions.
