Billy: Uh...that's Greek to me.
Jennifer: That means they have tapered legs.
Billy: Well, mine are baggy. They're the kind of pants you can lounge around in.
Jennifer: Mine are, too.
Billy: So maybe we shouldn't go out after all.
Jennifer: Yeah. Let's just lounge around!
That's Greek to me. 　

Greek是「希臘文」，十分冷僻難學，所以這句話的意思是「我不懂，我無法理解。」
tapered legs 　 褲腳收窄的剪裁
lounge around 　 （在室內）閑晃

A: How do you spend your week off?
你休假的禮拜都怎么過？
B: I just lounge around the house.
我就待在家里閑晃。

比 利：呃……我鴨子聽雷。
珍妮花：那是指這是AB褲。
比 利：我的是寬松剪裁。這是那種穿來在家里東晃西晃的褲子。
珍妮花：我的也可以啊。
比 利：其實我們或許根本用不著出去。
珍妮花：對啊。我們待在家里晃就好了。
