Voltarén is the Spanish brand name for a diclofenac gel rubbed on muscle pain, sprains and backache, which is exactly why Álvaro Ojeda shouting it works as a joke. Ojeda, a Spanish commentator known for loud, theatrical online rants, became a staple of Spanish language meme pages and shared audio clips. The shout spread as a ready made reaction for any minor injury, with editors dropping it over sports clips, falls and everyday complaints, and it remains popular because everyone recognises the product and the overreaction.
