AC/DC 条 @LDOCE

Oeasy

读到 AC/DC ，发现朗五双解只有一个义项：
# G/ [- d  D" t" O5 `5 o5 n
- I0 v/ Q1 }8 D

adj informal
sexually attracted to both men and women 【非正式】 双性恋的

( D9 _4 e3 ]9 G2 D$ g       
这和我的认知有差距，这 AC/DC 不就是交流电/直流电吗？怎么连这个意思都没有。又查了下，发现 LDOCE4 和 LDOCE6 这条内容分别如下：
LDOCE4 双解

1   informal sexually attracted to both men and women 【非正式】 双性恋的
% }. `5 K9 c0 M; m1 q7 ]) l7 _- D2   used to refer to electrical equipment that can work on either ALTERNATING CURRENT or DIRECT CURRENT 交流电直流电两用的

LDOCE6 http://www.ldoceonline.com/dictionary/ac-dc

看来朗文4双解也不能丢，还得和郎5双解一起用

西方这几年政治正确真厉害啊，与HOMO有关的词条少了就不行大概

MED online 里 AC/DC 释义也不含 交流电/直流电，要单独查询 AC、DC 才行。

3 z2 C8 a0 F) ~% ^LDOCE5 Viewer.exe 里 AC/DC 释义与朗五双解相同，Word Origin 是讲电流：

朗文和柯林斯手机app的解释

. B: ^8 K: q/ E4 g: ~" Z9 AEncarta的解释还是不错的：

) {2 ~1 A. z! j# i2.  offensive term: an offensive term meaning bisexual (slang)

; A7 n5 Q% c# VAC/DC (adj.) Look up AC/DC at Dictionary.com
* `4 \9 w! o1 D+ ?1 }4 Gelectronics abbreviation of alternating current/direct current, by 1898. As slang for "bisexual," 1959, said to have been in use orally from c. 1940; the notion is of working both ways.

但是：
http://www.collinsdictionary.com/dictionary/english/ac-dc
C20: humorous reference to electrical apparatus that is adaptable for alternating current and direct current
: @  I0 x1 P$ x) K4 _Collins的这个解释是否有点儿问题？
8 V' G8 H! `. D9 s, Q: ?
4 T+ t6 e8 W. l4 vODE也不错：
https://en.oxforddictionaries.com/definition/AC/DC
1  Alternating current/direct current.
2  informal Bisexual.

+ t/ m6 X+ p* K3 m% o% o从多个词典义项和下图可以看出，AC/DC连用表示直流/交流共用的含义现在不太使用了。
