In Spider-Man games "Maximum Carnage" and "Separation Anxiety" there is a secret move that you can do after pressing up and alternating between two buttons quickly to spin enemies like a pizza.

This is a direct reference to the ZX Spectrum game "Street Hassle" / "Bad Steet Brawler" / "Bop'n Rumble"

When shit was already real enough, and then it gets "REALLY REAL".
