Video description, from the Velcro brand YouTube channel:
Our Velcro Brand Companies legal team decided to clear a few things up about using the VELCRO® trademark correctly – because they’re lawyers and that’s what they do. When you use “velcro” as a noun or a verb (e.g., velcro shoes), you diminish the importance of our brand and our lawyers lose their insert fastening sound. So please, do not say “velcro shoes” (or “velcro wallet” or “velcro gloves”) - we repeat “velcro” is not a noun or a verb. VELCRO® is our brand. #dontsayvelcro
