Fast Jack

The act of masturbating very quickly when given a narrow window of time. Usually occurs when there is a brief period of time when one can masturbate without being seen by others.

I got a lap dance from that hot chick at the strip club and then I went over in the corner and had a fast jack while no one was looking.

Dirty FastJack 

When you’re playing Xbox and you kill somebody and they spawn behind you and start fucking you with a used sock and then finish in both of your ears. Then they will keep fucking your mouth until the semen in your ears comes out of your mouth

Wow a dirty FastJack gets after it
