生气撒娇耍赖皮
[shēng qì sā jiāo shuă lài pí]
It describes actions of sulking and acting spoilt when mad. '生气' (being angry), '撒娇' (to act coy or act cute, generally seeking for indulgence or comfort), and '耍赖皮' (acting like a brat, often unwilling to follow rules or give in). Used in playful self-deprecation, this shows a more immature but lovable response to disappointment.
