Don't keep pushing him. He's going to go Jack-Jack.

jack jacked

When a guy is jacking off and is interrupted by a second individual who "lends a hand" and finishes the job.Ideally,the interloper could be the wife,girlfriend,a hot maid,or cute neighbor girl. Strangely,the good samaritan could be a sister,grandma,brother or roommate.

I was choking the chicken when my sister's hot friend barged in the bathroom and jack jacked me.
