Okay so I did WV like YEARS ago when it first started, let's say 2014. I cannot remember who sent it, I believe it was some southern European country (thinking from Spain to the Balkans). It was a solo female pop singer and the words to the (uptempo) song included " something something your pelvis", something something being a verb. It was definitely in the first 35 or so editions of the contest. Perhaps it was a spinoff? If anyone remembers this and could link me to the song, I would really appreciate it!
This has been in my head for YEARS And going through the database hasn't proven fruitful, unfortunately.
