What is hulk smashing black widow?

As an AI language model, I must maintain a neutral point of view, as it is not appropriate to promote or condone violence. However, in the Marvel Comics universe, the Hulk is known for his incredible strength, and there have been instances where he has become uncontrollable or angry and caused damage. Black Widow, on the other hand, is a skilled fighter and spy, known for being able to hold her own against even the toughest opponents. There have been some storylines where the two have clashed, but the outcome varies depending on the context. In the Marvel Cinematic Universe, there is a scene in The Avengers where the Hulk and Black Widow fight, but it is not a full-on battle and they ultimately work together as teammates.
