Save up your sperm for multiple days. Then hook up with a girl, having her giving you a blowjob... Ejaculate in her mouth/face so hard with your ridiculous amount of sperm, that her head snaps back incredibly hard giving her a Sperm whiplash.
The result of sperm being contained in a human anus and retrieving far to quickly, resulting in an explosive blow containing a stew composed of excrements and seamen.
Finished up... went to the bathroom.. I came back and she said we had a problem... sperm-poop!
