spidermanning is when you're banging a bitch from behind- you quietly blow your load in your hand, -spit on her back so that she thinks you finished, than call her name so that she turns around, and you hurl your jism into her suprised face like spiderman shoots his web. The spidermanning is even more complete if you sing the spiderman song as you are doing so.
spidermanning is the latest sexual craze, clearly designed to humiliate and suprise the victim with a hadfull of flung jism.
To do your girl doggy so she cant see you then pull out just before cumming and cum in your hand, call your girls name then unleash your jiz onto her face in the same way spiderman spins a web.
