A variation of the Spiderman sex act. Doing a girl from behind, you finish in your hand, while spitting on her back to allude to being done. When she turns around, the difference is made by rubbing the handfull of semen into her eyes, rather then throwing it in as per the Spiderman.
Some people say that black sabbath gave birth to metal, and metallica raised it. this is not true, VENOM were formed before metallica, and paved the way for today's real, black metal, which is way better than any of the americanised crap that metallica paved the way for.
When you're banging someone in the ass, you blow your load in said ass. Then you pull out not knowing the individual you were sodomizing had explosive liquid diarrhea painting your chest with a Venom-like design of jizz and liquid shit.
Man, I was banging that chick in the ass last night. When I pulled out she totally Venomed me. I wish I didn't take her to Taco Bell for dinner.
