你长得跟闹着玩似的你长得跟没吃药似的
[nĭ zhăng dé gēn nào zhe wán sì de nĭ zhăng dé gēn méi chī yào sì de]
'You look like you're playing around; You look like you forgot to take your medicine' combines humor with criticism, suggesting that the other person's appearance or actions seem out of place, unusual, or even bizarre, possibly implying immaturity or a need for composure.
