An original name for the penis, somehow summing up the action taking place during sex as well. An epic word the kind of which the world is sorely lacking.

Perfectly encapsulates the wild originality that can be had in the bedroom, or indeed in a park with everyone watching.

If you claim to have a Gristlehammer you may be required to prove it. Hence this is a bold claim.
Did you bang that girl last night?

You bet, I nailed her pussy into the pleasure zone with my Gristlehammer.

----

I got a big dick.

Oh yeah? I have a mighty Gristlehammer that would make Thor himself jealous.
