Inserting one's middle finger and ring finger into the female canal known as the vagina. When performed properly, the remaining fingers make up the ever so popular "Ozzy" or "Rock" hand sign.
Josie and Franklin began their typical foreplay, but Franklin popped in his favorite 80's rock mix. As soon as he heart Crazy Train, he stuffed Josie with The Rocker, what a lucky broad.

Similar to the shocker, but for men. The middle and index finger are inserted into the mans anus, pleasuring the prostate, while the thumb is wrapped around the balls, separating the testicles slightly. A back and forth "rocking" motion completes this action.
"That chick was down for anything! She even gave me the rocker!"

Similar to The Shocker, this hand-based sexual act uses the extended index and pinky fingers, while the ring and middle fingers are curled down/held in by the thumb, making the popular "rock and roll" hand gesture, used at concerts. The index finger is then inserted into the vagina, while the pinky is inserted into the womans anus.
Before giving her the Shocker, I warmed her up with the Rocker... next, it's on to the Spocker!

The Rocker, (a popular sex position) is the meeble act of cutting the gap between your female partners asshole and pussy (with a scissors or blade) and using the gap as one long hole making cowgirl/reverse cowgirl in a rocking form.
she needed 87 stiches after her and her boyfriend tried the rocker last night...
