“Pig-headed”是什麼意思？
其實，“Pig-headed”的意思是：頑固的；固執的；愚蠢固執的。
You're really pig-headed.
你真是個又蠢又固執的人。
Big head ≠ 大頭
先看看英英解釋：If you describe someone as a big head, you disapprove of them because they think they are very clever and know everything。所以，“Big head”的意思是指：自負的人。
He's always boasting. He's such a big head!
他老是吹牛。真是個自負的傢伙！
Pig out≠豬走了
其實，“Pig out”的意思是：（像豬一樣）大吃大喝。把Pig用在這裏，是不是一下子就生動起來了。

讓我們大吃一頓吧。
Lose your head ≠ 丟了你的頭
“Lose your head”真正的意思是：失去理智；驚慌失措。
You'll be OK as long as you don't lose your head.
只要你保持理智，就沒事。
