Milwaukee Slimer
The act of hiding in a girlfriends room covered in a white sheet dressed as a ghost. Then, when she is sleeping you spook her and ejaculate on her creating a scenario in which a ghost haunted her and touched her with its ectoplasm. You then knock her out and proceed with the Milwaukee Ghost Buster.
"So guys, I think its time for the Milwaukee Slimer. She will never see me cumming."
