Help parsing つまんないないんだよ


I have a question about the grammar (assuming it is grammatical and not
figurative) in the following line from the song ときめきポポロン from the anime
ご注文はうさぎですか？.

> つまんないないんだよ

I think the meaning is pretty clear (we won't be bored) but I'm curious about
the seemingly extra ない. Would つまらないんだよ have the exact same meaning? Is it
common to add ない to いadjectives for emphasis?




ない can be repeated many times for emphasis (ie. ないないないない… ≒ No, no, no, no,
no...) even in ordinary conversations, and it just means **"absolutely
no/impossible"** regardless of whether the number is even or odd.

つまんないない is certainly ungrammatical in everyday writings, but since it's a
song, I think this just means つまんない (boring), emphasized in a peculiar way
only found in lyrics.

easily find similar examples of repeated ない:

> **足りないないない** 夜明かしでも  
>  **せつないないない** ごまかしてんだ

>  (snip)

> **全く関係ないないないないない** とか 言い散らかして

Well, there are only two ない's in ときめきポポロン, but [after actually listening to
the song](https://www.youtube.com/watch?v=qk9pucVX2nk), I think it's safe to
say this (つまん)ないない is used in the same way as the above.
