man-o-plasm 

Man-o-plasm refers to a 'load' of very viscous, cloudy white semen that is ejaculated from a man's wanger upon orgasm. It is named 'man-o-plasm' as it resembles the eerie substance that ghostly apparitions are said to leave behind (made famous in the movie Ghostbusters).

Egon: shit, then it's just a load of man-o-plasm. Goddamn Ray, you filthy cunt.
