Does the 擬態語 word もやもや have a slang meaning of "horny?"


In an informal conversation with a new friend, I was discussing 擬態語. She
offered the word もやもや as an example, meaning "to be horny (i.e.., desiring
sex)." After clarifying the meaning, I left it at that. When I looked it up I
see this definition:

> もやもや moyamoya · モヤモヤ
>
> adverb / noun or participle with aux. verb する → conjugation: hazy; murky;
> misty; foggy; fuzzy; —Onomatopoeia.
>
> 「あっぱれ！」天使はそういうと、稲妻が走るもやもやの煙の中へ消えていった。 "Done!" says the angel, and disappears
> in a cloud of smoke and a bolt of lightning.
>
> adverb / noun / noun or participle with aux. verb する → conjugation: gloomy;
> feeling depressed; feeling sad; —Onomatopoeia.

In any case, it is apparent that Tangorin.com is making a mistake in calling
this word onomatopoeia, as it is a mimetic word instead (apparently a
Phenomime.)

Is it also a psychomime expressing the state of horniness or did I hear wrong?
If I heard wrong does such a psychomime exist?

I would ask this friend directly, but I have a girlfriend and am wary of
initating what could be a flirtatious conversation.

*Edit: Kotobank has this definition so I think I heard right:

> 色情がむらむらと起こるさま。「数々の通はせ文、清十郎も―となりて」〈浮・五人女・一〉

Is this expression common and easily understandable? Is the meaning different
than むらむら?




Based on my experience, it seems that "もやもや" meaning "horny" isn't common
nowadays.  
Yes, as you say, I found out that "もやもや" _does_ have meaning of "being horny,"
but note that the example came with the definition
(「数々の通はせ文、清十郎も―となりて」〈浮・五人女・一〉) is written over 300 yrs ago.

Instead, I often hear "むらむら" to depict it.  
(According to [this page](http://zokugo-dict.com/33mu/muramura.htm), using
"むらむら" to depict "being horny" is new.)

We do use "もやもや" to depict:

  * mist/smoke **hanging over**
  * thing/situation **being unclear**
  * **being unhappy/depressed**
