Spider-Man Grip 

The position of female masturbation/fingering in which her middle and index finger are moved consistently inside of her vagina in a trigger movement, resembling the finger movement that Spider-Man uses to shoot webs (this position can also be used by a male to the female).

-Person 1: I walked in on her spider-man grip fingering herself HARD dude
-Person 2: wow. H O T.
