What's -her-face 她叫什么来着

Li Hua正在往图书馆走，突然，Larry把她叫住了。

LL: Hey, Li Hua. One of your classmates asked me to give you this envelope.

LH: 我的同学要你给我这个信封？哪个同学呀？

LL: Oh, it was... what's-her-face, you know, the tall girl with red hair.

LH: 高个子、红头发的女孩儿？你还说什么- What's her face? 哎，Face不是“脸”吗？

LL: I said "what's-her-face" instead of her name because I couldn't remember her name. I guess it means I can remember her face, but not her name.

LH: 噢，你不记得她的名字，但是你记得她的脸长的是什么样子，所以你说what's her face, 也就相当于what's her name 。Hm，Larry, 你这么说是不是不太礼貌呢？

LL: Well, it's not really rude, but it's very informal. You shouldn't call someone what's-her-face if she is nearby... in that case, you should just ask her what her name is.

LH: 哎哟，幸亏你告诉我， 尽管what's-her-face是很随便的说法，但是也不应该当着那个人的面这么说。要是这个人就在你身边，那么我就应该直接问她叫什么名字。哎，对了，Larry, 刚才你是说what's her face, 要是男孩子的话，那应该怎么说呢？

LL: You would say what's-his-face.

LH: 噢，要是男生，但是又记不起他的名字，那也可以说what's his face。我想起来了，那个高个红头发的女孩是Julia。我和Jenny向她借了上星期四的笔记，因为那天我俩没去上课。这个信封里肯定是她的笔记。

LL: That's right - You missed a class last Thursday. Hey wait, if you needed notes, why didn't you just ask me?

LH: 但是我们觉得 - what's-her-face... um, Julia... 她肯定比你记得好。

LL: Well, come to think of it - If I were what's-her-face, er... I mean Jenny, I wouldn't want my notes either.
