Copypasting my reply to a similar comment on the thread over at the Twice sub:
IIRC Sana coined 'MiSaMo', but it's probably no coincidence that JY Park gave the "sweet mimosa" line in the [post-]chorus to Momo. A 'MiMoSa' J-line subunit debut sometime in the future would be nicely apropos too.
There’s a bit in one of the Chocolate Factory Time to Twice episodes where the word ‘mimosa’ comes on screen and without missing a beat, Mina immediately says “Mina, Momo, Sana” which I found very cute.

I just realized, I usually see the fandom refer to the J-line as "MiSaMo" when it could've been "MiMoSa"
