When you catch someone masturbating and use it as blackmail against them.
Hey man, can your bro give me a ride to the movies?
Yeah sure, he does whatever I tell him to because I got some dirty jackmail on him.

Get the mug
Get a Jackmail mug for your mate Nathalie.
When a musician uses info he gathered in confidence through assumed trust uses that info to further himself and his career. Combination of jacking and blackmail.
Don't share that info with him or he'll jackmail you for a booking.
