Oral Jackhammer

When your partner lays on their back on the edge of a bed with their face up. They perform oral sex in a vertical motion while you “jackhammer” their face holding their wrists as handles. The “jackhammer” also makes the sounds “Dadadadadada” as to replicate a jackhammer sound.

“Kathy, if you don’t shut your mouth I’m going to give you an oral jackhammer!”

Jihadi Jackhammer

(verb) Conducting the sexual performance of, as a male partner to a female counterpart, sawing off your consenting or non-consenting partner's head with a rusty, World War II-era bayonet/hacksaw, or any second-hand bladed instrument you can possibly acquire and use, and then aptly proceeding to violently and callously copulate with their severed head into the sand of a hot, dry Saudi desert until the surface of their cranium is no more visible.

A classic, culturally promiment coming-of-age ritual in the ranks of Citroën-sponsored cornershops and independent, small street businesses located in the general area of Bradford, Leeds, etc...

Muhammad : Aisha came home from work 5 minutes later yesterday night. I do firmly believe that a Jihadi Jackhammer is in order.

GP : Yes.
