Mushroom hammer

When a female grabs the shaft of an erect penis, then using her other hand makes a fist and a hammer motion, smashing the head of the penis.

So jake pissed a girl off again last night, and during what he believed was his victory blowjob for winning the argument he was brought to the fetal position with a brutal mushroom hammer.

hammer wank

when there's not full access to a penis and so a full grip of the hand cannot be obtained such as in the cinema when your dicks inevitably through the bottom of the popcorn box, so the index and middle finger become like the claw of a hammer and the penis being like the nail that's being pulled giving a better grip

Was sittin in mass and Jess gave me such a hammer wank

Heel Hammer

To kick one's self in the testicles with their heel, while sitting in a chair.

Heel Hammer - Scoot to the end of your chair and let the "boys" spill of the edge. Now raise either foot (or both) and give the giggle berries a good whack.

hammer space

Hammer space is the place where anime girls get their weapons from (normally, as the name suggests, hammers). This term was coined probably because anime-watchers were always wondering where on earth the girls carry their huge mallets or hammers. They seem to appear out of nowhere...well, that nowhere is Hammer Space!

With an enraged look in her eyes, she reached back behind herself and pulled a giant mallet out of Hammer Space, then started to beat the perpetrator unrelentingly.

Meat-Hammer

Usually in reference to an abnormaly large penis with a large circumference.

"All I remember is a flash, a scream, and a thud as the Meat-Hammer pummeled my interior!"

Bird Hammer

A violent sexual act between a male and a female whereby the male places his arm around the head of the female, shapes his fingers into bird or sock puppet like manner, inserts his hand or “Bird” into the naughty bit of the female and finally knees his elbow ferociously to induce a hammer effect.

Whilst the bird hammer has come into trend in the recent years many believe it originates from Auguste Rodin’s “The Thinker”.

“Yo, dog what’s the go with that girl you’re dating?” “G-unit, I can’t take her seriously I bird hammered her on the second date..” *Lolz* *Hi 5*

“I can’t believe she dumped you!” “Don’t worry, I gave her the bird hammered her throughout the breakup sex” *Lolz* *Hi 5*
