Not sure where we lost you, but I don't blame you.>>4075
is the famous "Caramelldansen." The song is in Swedish, but became popular as a meme in Japan with some of the lyrics being misheard as Kansai-ben. In Japan it's colloquially known as the "Uma Uma Dance" (potentially either "Horse Horse dance," or "Yummy Yummy Dance").
The first line of >>4078>eansa med oss, klappa era händer
translates to English as "Dance with us, clap your hands,"
but also sounds like, "barusamiko-su yappa irahen de" (バルサミコ酢、やっぱ いらへんで), which roughly means "Turns out we don't need any balsamic vinegar" (in Kansai dialect, which is the region Osaka is from).
There's also an episode of Lucky Star where Tsukasa gets briefly obsessed over balsamic vinegar (or at least the words "balsamic vinegar") so there's a good deal of fan art featuring her with a bottle of balsamic, which is why I posted that.https://en.wikipedia.org/wiki/Caramelldansen#Internet_phenomenon
