What is the meaning of ルンパッパ？


I've noticed the word ルンパッパ (runpappa) is used in the KEMU VOXX series of
songs, but I don't know how to translate it. Using google translate just
returns rumpappa, which isn't an English word. I've tried googling it, but it
just returns Ludicolo, which certainly isn't relevant. The top result says it
means to sin, but it also says their source may be unreliable. The three songs
to use it are [Haikei Dopperugenga](https://youtu.be/grdy6rLbQ-c "Haikei
Dopperugenga"), [Inbijiburu](https://youtu.be/vXSpdipuiFs "Inbijiburu"), and
Kamisama Nejimaki. Thanks!




That is a mimetic word to feeling the rhythm of a song. So translate it into
"Rum-pa-ppa".

Rumpappa is the word combined "Run-run" and "Um-pa-ppa"

"Run-run" is a mimetic word expressing good/happy mood.

"Um-pa-ppa" is the title of song. This word is familiar with Japanese as they
sing it when in primary school.

"Um-pa-ppa" is "Oom-Pah-Pah" in musical "Oliver!".
