So it's catchy and there's actually Ketchup in the music video.

Because ketchup makes an exclusive appearing in the rookie's music video, I advise everyone to watch it.  I assume that this ridiculously named song is about ketchup (and probably boys/dancing since majority girl group songs are about boys or dancing or boys and dancing)  The ketcup is pretty sexy tbh.  10/10 would... not eat because I don't like ketchup unless there's a lot of mustard in it.

*still judging so hard*
