Spider Grip 

A male masturbatory technique where the man interlocks his fingers, pinky to pointer, so the knuckles are touching. He then places his penis in between the "spider legs" and uses the grip to pleasure himself. This grip often involves the use of the thumbs on the head of the penis. The use of thumbs is often referred to as "Chelin" in reference to the name of a spiders mouth parts.

I'm not a big fan of the stranger, I think the spider grip feels way better.

My gf spider gripped me last night and it was amazing. She even chelied it!

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 2: wow. H O T.

spidey grip 

Utilizing a finger pose just like the famed web-slinger. Extend all fingers with palm up and fold the middle inward. Then, put one in the stink and two in the pink of your chick du jour.

All I had to do to see the whites of her eyes was to put the spidey grip on her.
