look up any word, like blumpkin:
 
1.
A style of hand job, not to be confused with a sand job. It takes place when the penis is grabbed and thrown about in a very random matter (shaken).

If girls want to perform this sexual act:

-grab shaft of penis extremely loose like.
-shake in a random semi violent manner.
-do not stir
I totally thought I was gonna jizz everywhere last night until this girl came back to my room and gave me the shake job to never forget #brutal. I would rather of gotten a sand job.
