Military slang for getting assigned to Fleet Assistance Personnel. Basically it's when your unit is required to temporarily send X number of warm bodies to do menial tasks for the base or the squadron or something, and you're picked to be part of the group. Occasionally a cool gig and a welcome break from routine, but a lot of the time it's something godawful and involves Twentynine Palms or the term "grease trap". Usually assigned to new arrivals as a rite of passage, and to shitbags that aren't wanted in their unit

To masturbate when a man gets a boner, but he wasn't particularaly looking to get a boner. So, he must masturbate, or fap, in order to avoid the dreaded blue balls.
I was just watching TV, minding my own business, when I stumbled across a movie set on a beach with a gorgeous blonde, 36-24-36, jogging around in a too-small bikini with her nipples poking out, tits shaking like water balloons. Naturally, I popped a boner. But, since I'm single, there was no one home to satisfy me. Angrily, I said to myself, "I guess I'll have to fap it out. I'm really not in the mood for blue balls tonight."
