slow jack 

To masturbate at a reduced pace. Sometimes performed for hours at a time.

"Yo man, slow jacking has so many benefits. Why just the other day I was cooking while I jacked, try the oven mit, it's just like givin' yo'self a stranger."

Taking a lot of time doing something by yourself, that could give you the cover to masterbate

We were waiting to go to the club while Drew was getting ready, slow jackin it for an hour.

You better not be slowjackin it while we are gone.

We would have been here earlier, but Andrew was slowjackin it all day.

slowjack

The act of borrowing something from a friend with the intent of returning it, yet you never do and end up keeping it.

I loaned my friend a CD and he slowjacked it from me.
