After a guy spiderman's you, you kick him in the balls and wipe his own jizz into his face while he's doubled over. Proceed to do the spiderman web slinging poses and then stand like a proud female superhero while he learns his lesson.
My boyfriend spiderman'd me last night so I spiderwoman'd him back. He'll think twice before doing that again.
The reverse spiderman. Where a guy jizzes in a chick's hand and she throws it back in his face and pulls a spiderman on his ass: throwing the splooge back in his face like spiderman's web, pulling the imaginary web rope as she gets up to assume the superhero pose.
Mike was about to ejaculate in Ashley's mouth, but she pulled back and he came in her hand and she surpised him with a spiderwoman... His life will never be the same!
Female with a single extraordinary power. Having never visited her minge with a razor, she has a magnificent array of spiders legs protruding from her knickers thus being able to render any man into a state of shocked horror at a hundred yards.
Beach Dude 1 (dazed): "Whoaaa ... did you see that chick's bikini-line?"
Beach Dude 2: "Yeah ... like it must've been Spiderwoman."
