The Hard-on of all Hard-ons. A exagerated hard-on that one gets only two to three times a year and on every other leap year. A penis on steroid effect that enables its inhabitor endless sex. Symptons include a ripped burning feeling often upon onset, enlarged vessles, a purplish/blue pop-top, a chissled marble like texture, added girth of initial 1/3 of shaft and added overall length. Often the scrotum will tighten up and almost disappear as if the testicles have joined powers with the penis. WARNING-All women should be on the look out for these characteristics especially on one night stands as women have been known to be subject to injury.
