The word "rag" in the context of a porn video tag is most likely referring to "Ragging," which means rough or forceful sexual activity. This tag denotes a scene that involves such activities, where one partner might be restrained, dominated, or forced into engaging in acts they may not be consenting to. Ragging can be both physical and verbal, and it's crucial for viewers to understand the difference between consensual BDSM play and non-consensual rough treatment when watching such content. This specific tag indicates that there might be elements of dominance, forcefulness, and non-consent in the scene.
