・hit one's butt as punishment・smack one's butt as punishment

「打屁股」可以用英語 hit one's butt as punishment 或 smack one's butt as punishment 來表達。

※說到「屁股」，雖然比較可能會想到 hip ，但是 hip 該說是哪個部位，比起屁服，應當指的是腰部以下的側邊區域。

If you do that, I will hit your butt as punishment.

（如果你這樣做，我就打你屁股。）

When I was a child, my mother often smacked my butt as punishment.

（小時候，媽媽常打我的屁股。）
