When you need to ejaculate (or 'bust a nut') so bad that you start hallucinating erotic images around you, much like a mirage.
Tom: Yo, I was in this super long ass meeting the other day, and I needed to bust so bad I started Hallucinutting near the end!
Paul: What? I thought that was just a joke?
Tom: Nah, bro. I was totally seeing hot strippers on my desk and shit!
