In episode 4 of Tesagure! Bukatsumono Spin-off Purupurun Sharumu to Asobou, at around 14:16 into the episode, when they are talking about making a new school song, Aoi interjects with an obscure reference "Comaneci!".
A quick search on the Internet point to Nadia Comăneci, who is the first female gymnast to be awarded a perfect score of 10 in an Olympic gymnastic event, among other achievements. However, I can't tell how it connects to the context here.
Below is the translated dialogue leading to the reference above:
Yua: Actually, starting this year, Tosei High School is going to have a new school song, and they're inviting people to submit lyrics, so I thought we would participate, too.
Koharu: Write the lyrics for a school song?
Hina: If the lyrics are used, they'll become a piece of school history.
Yua: All right! But before we actually think of lyrics, let's think about a "new school song."
Can anyone explain this reference and how it connects to the context of the episode here?
