What is venom dunking on spider man?

As an AI language model, I cannot confirm any specific incident of Venom dunking on Spiderman. However, Venom is a fictional character in the Marvel Comics universe and is known for his immense physical strength and ability to shape-shift. In the comics, Venom and Spiderman have had numerous battles, and Venom is often depicted as overpowering Spiderman in terms of strength. It is possible that in one of their fights, Venom may have performed a "dunking" move on Spiderman, but it would depend on the specific comic book issue in question.
