Piss Hard-On (or Hardon): A graphic way to describe the male condition of waking up with a very stiff erection coupled with a need to urinate. The leading causes of this syndrome are thought to be: 1) a full bladder rubs against the prostate gland which then arouses the rest of a man's sexual machinery as though getting ready for intercourse; or the more recent theory, that 2) during a routine night's sleep, a man will have four or five erections but usually they don't awaken him. This is probably the body's way of running "routine diagnostic checks" on his various systems, including sexual readiness. The one that wakes you up either because it's time to wake up or because you're dying to go to the bathroom is the P.H-O.
