Doing a Spiderman 

Doing a Spiderman is when a male ejaculates into his hand and proceeds to throw it at an unsuspecting suspect while adding a very satisfying "pssssttt" like noise to simulate the sound of the web but in this case the sound of the seamen being tossed from his hand.

Bob saw an a woman across the street he decided that he would do a spiderman. since it takes bob a short time to ejaculate he was ready in a jiffy. He proceeded to charge up to the lady whilst screaming his war cry, (this caught her attention and she turned) he then threw his seamen in her face and ran away with a grin on his face.
