The phrase like and subscribe with all notifications comes from the standard outro language that developed on YouTube as creators began asking viewers to enable the notification bell for new uploads. Short spoken versions like this one spread through meme soundboards and editing communities, where they are reused both sincerely and ironically. It remains popular because the request is understood instantly, even out of context, and because placing a familiar creator outro over unrelated footage creates an immediate joke about internet video culture and self-promotion.
