When you are flirting up a shawty and then a douche bag comes up and prevents you from motor boating her rack. Also a synonym for cock blocked.
Brian was getting major pussy when Britain, a pretentious douche bag, comes right in the middle of their banging and ruins everything for everyone. Brian has officially been rack jacked.

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.
