Usage of くせに and わりに in the following sentence


In Nihongo so-matome N3 grammar p63. In question I number 3 there is this
question written where both answers seems fine to me.

  * 男の(a.くせに,b.わりに)、女みたいだ.

The answer is くせに.

Isn't わりに used when an unexpected feeling occurs? for example here the normal
is that for being a boy he is supposed to look like a boy however he look like
a girl. Also くせに makes perfect sense to me. Why くせに is the correct answer?




I think you need to look at more than just the English translations to get the
way わりに is used.

くせに can be used as a [somewhat ruder replacement of
のに](http://www.jgram.org/pages/viewOne.php?tagE=kuseni), so it makes sense to
say that here. (の there is a nominalizer with no particular meaning of its own
whereas くせ has meaning).

In contrast, わりに used to be written as 割に which helps make clearer what it
does.

Specifically, it it says "As much/little as X, _[unwritten: one might infer
Y]_ , but surprisingly Z.

I think the problem for the example sentence is 男 is not a proportional fact X
of the relevant sort.

All of the examples being offered online are like:

> 年の割には若く見える. [here](http://japanesetest4you.com/flashcard/learn-
> jlpt-n3-grammar-%E3%82%8F%E3%82%8A%E3%81%AB-wari-ni/) [also

= he looks young if you take in account his age [which should make him look
older]

> お金がないと言っている割に、よく旅行するね。 [here](http://www.jlptsensei.com/grammar-
> lesson/warini/)

= as much as she says she has no money, she seems to travel a lot.

the basic pattern is we need some sort of proportional claim and then a second
fact to the contrary.

You don't have that in the sentence above, so it can't be わりに

I think when they're saying "unexpected feeling" they mean that the expression
includes some opprobrium. As in we're annoyed at this outcome. (cf.

> お金がないのに、よく旅行に行きます。

= even though she doesn't have any money she often travels. (perhaps because
she collects airline miles)
