RPJ 

This mysterious, raunchy acronym may finally put some disputes to rest. While originally meant to refer to a lover that is the only one that can provide a carnal experience of extraordinary proportions, the term also evolved (or devolved, depending on who you ask) to refer to an orgasm that is highly above average.

The term started to be used on New York college campuses in the late 90s, as a reference to the lyric, "Bustin' makes me feel good!" by 1980s recording artist Ray Parker, Jr. This definition is the original, referring to a unique sexual partner that consistently provides an above-average sexual experience.

The later, more graphic acronym refers more specifically to the act of orgasm itself, where the letters stand for "Rocket Propelled Jizzload". It is believed that this definition was started on campuses where the acronym had migrated from other schools but those who heard it did not let on that they did not know its original definition. Some say they can be applauded for their X-rated interpretation.

Well, just as I expected, man. Danielle and I finally hooked up, and words cannot even describe how many ways she rocked my world. Seriously, total RPJ, man! Total RPJ!
