A variation of "The Shocker" (an uninvited digit placed in the girl's anus ) in which, with the finger still up there, you "hook" back in the direction the pussy. No real purpose here other than to think to yourself while doing it, "ahhh yes the Fishhook......". Another variation called the "New Jersey Meathook" involves sticking your uninvited digit in the girl's anus while fucking her from behind. You finger is then turned upward toward her back and you pull her entire body toward you over and over while she is sliding on your cock.

When performing the act of sex while in the doggy style position and entering vaginally, use your index finger to slide in and out of her brown eye. If you realize your finger is becoming engulfed in matter of a brown nature, swing your finger up to her mouth and hook her like a fish.

Similar to the shocker, but afterwards the poo-laden finger is inserted to the womans or mans(in prison) mouth in a hooked fashion.

From the doggy-style position, you hook your pinky fingers in her mouth and pull back to achieve deeper penetration.
Last night, after watching Bass Masters on ESPN, I double fishhooked Lorraine so hard, I split her upper lip. It was fucking great!

Everson was quite ecstatic while instead of receiving the shocker, was treated to the boston fishhook.
