What does シンメ状態 mean?


I was watching a
[video](https://twitter.com/mounemasu_/status/927016483170873344) and I heard
this word "シンメ状態".

Somehow I believe I have heard this word before, but I still could not make
any sense of it from the dictionary.

> シンメ = ???
>
> 状態 = current status; condition; situation; circumstances; state​ (from

Was it some kind of phrase or something?




It's jargon used among Japanese アイドル fans, especially ジャニーズ fans.

シンメ is from シンメトリー ("symmetry") and initially referred to performers dancing
symmetrically in the mathematical sense, like a mirror-image.

Then it gained a broader sense among idol fans, and it now mainly refers to
two idols within a group who often perform together and are considered as a
"pair". For example, the person in the video mentions やまちね (山田涼介 and 知念侑李),
who can be considered as a シンメ in _Hey! Say! JUMP_. Most people in Japan know
nothing about やまちね and シンメ, so I think the person in the video said it to show
his knowledge about J組.
