What does ビクビクのヌルヌルで mean?

Question

What does ビクビクのヌルヌルで mean?

As for context, she was trying to remove the fish she had just caught from her fishing rod. It's clear that shes referring to the fish, but the の between ビクビク and ヌルヌル is confusing me as to what is being said.

What on　earth does びくびくのぬるぬる mean?

Answer 1

As stated in the comment section and in the other answer, ヌルヌル means "slimy", "slippery" and hard to grab hold of.

ビクビク often means "to feel scared", but here in your example it has nothing to do with "feeling scared". 明鏡国語辞典 explains びくびく as follows:

びくびく〘副詞〙 ❶ 恐怖・不安に敏感になっておびえるさま。 ❷ 体などが何度もふるえ動くさま。

We use ビクビク, ビクッ, or ビクン to describe a sudden and violent convulsive movement, as well as a 痙攣 (convulsion, twitch, cramp), so the ビクビク here is more like "to wriggle" or "to twitch", and indicates the sudden and quick movement of the fish. Here're a few examples of this use of ビクビク:

• 「睡眠中に足や腕がビクビクと動く」
• 「寝ているときに体がピクッと動いたりビクビク動いたりする」
• 「動かなかった魚が、ビクビク！！って動きます」

The の here is used to connect the two mimetic words, like "and". You can rephrase ビクビクのヌルヌルで as ビクビクで(その上)ヌルヌルで or ビクビクしていて(その上)ヌルヌルしていて, "The fish was wriggling and slimy". To me, ビクビクのヌルヌル sounds a little more emphatic than normal ビクビクでヌルヌル.

I couldn't find the definition of this use of の in a paper or online dictionary. I'll just quote a couple of examples from the web:

• 「道路(が)つるつるのてかてか！」
• 「金属をつるつるのピカピカにする」
• 「ギタギタのメロメロのボロボロにしてやる。」

Answer 2

Unless it's strictly G-rated (Doraemon, Anpan-man, ...), I'd guess that some suggestive humor is intended.

Do a search with　 [　ビクビク and ヌルヌル　]　 and you'll see ...

https://www.google.co.jp/#q=%E3%83%93%E3%82%AF%E3%83%93%E3%82%AF++++%E3%83%8C%E3%83%AB%E3%83%8C%E3%83%AB

     ( Every one of the top 50 hits is explicit material. )

I didn't realize that the expression ビクビク感じちゃう had become so common.

     Ok, i now see that strictly G-rated manga, novel, story, etc.
     would never use the combination  [　ビクビク  and  ヌルヌル　]
