Wait, maybe "Rollerblades Rar" is part of a YouTube video title they heard. Let me search for videos titled "Benson Boone Fireworks rollerblades rar." Let's see... Hmm, the first results are a video by an artist named Benson Boone called "Fireworks," but no mention of rollerblades. There's a video with someone rollerblading while listening to a playlist with his song. Maybe that's where the user got the idea. They might want to create a similar video or find a specific file related to that concept.
