1) Hulk is naked in this movie. We see Hulk butt. Thor reacts to the presence of Hulk dick. We know Hulk Dick is there and Hulk nudity is on the table. They took the time to cgi the butt. They have the model for the butt.
2) Bruce makes repeated reference to how tight Tony’s pants are
3) the Hulk got much bigger thighs etc than Bruce do
4) the clear and present conclusion to this is that in the final battle Hulk should have busted out big Hulk dick swinging like god’s worst battering ram, Hulk butt shining in the starlight, Hulk balls clapping together like the fucking doom boom doom of the ultimate battle drum
5) show us full frontal Hulk nudity you fucking cowards, show us the biggest greenest dong this world has ever seen, put it on our 3d imax screens, Disney, you have all the tools and opportunity you need
