The act of initiating and finishing a hand job in one, earth-shatteringly pleasurable pump. It cannot be completed more than once in any 24 hour span, or the receiver will die a horrible, agonizing death.
Feeling spicy, the middle-aged man asked for an OPHJ. The crazy lady obliged...steadied herself, and in one quick motion finished the man off with a loud yell followed by a quick jerking motion. Groaning, the man immediately fell asleep on the floor. Thus, she had performed the fabled one pump hj.
