When you are banging a chick from behind, you cum in your hand and spit on her anus, thus making her think you have ejaculated on her, when she turns around you throw that shit at her in a spiderman-esque fashion.
I was banging this bitch, then I pulled a spiderman on her.

When your fucking a girl (Doesnt matter which way) and right before you about to cum you pull out. You then jizz on your hand and mimicking spider-man throw your jizz in the girls face, while yelling "GO WEB GO!"
"Dude, you seriously gave the bitch the spider-man?

When dancing with a girl at a frat/bar you place your hand down the front of her jeans and slide in Spiderman fashion (middle and ring finger inserted with other three fingers out to the sides a la Tobey Maguire). Singing the Spiderman theme song adds to the ambiance.
Hey Jimmy I saw you Spiderman that chick on the dance floor last night. She must have been really wet.
