When, upon lifting immense weight on bench press, one becomes incredibility turned on by their accomplishment. A "Rack-n-Jack" participant will then rack their weight and immediately begin masturbating in the gym.
Damn, I was pissed I couldn't get more reps last week at my new max. I was so impressed with myself that I rack & jacked it right there before I could finish my set.

The Rack Jack Bandit is an anonymous man that appears across US NAVY ships only when at sea. He approaches in the dead of night to give his victims ruthless handjobs in their racks (bunk beds) while they're asleep.
