The art of a faked male orgasm. Pretending to ejaculate. When you grow weary of having intercourse with a female you may "ghost bust a nut" to end the experience.
Rodney: So...I got drunk and hooked up with this girl last night
Maurice: Really dude? Nice!
Rodney: Nah man, not nice! This chick was gross! When I finally sobered up I had to ghost-bust a nut and got out of there!
