It all starts when a girl is sucking on your balls. You tell her to go lower, lower, lower, until she gets to your chocolate starfish. Then you flex your abs as hard as you can and blow ass in her face. If you accidentally shart you have successfully performed the infamous dirty hammer.

The Dirty Hammer is a spin off of the original hammer. It begins when a girl is sucking on your balls and makes her way down to your chocolate starfish. Once she is there you proceed to execute the hammer, but you shart performing the awe inspiring Dirty Hammer. If chunks or squirts of feces do not exit your chocolate starfish, you suck at life and should be reading the hammer.
