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.
I hate the term "Piss
Hard-On". It's ugly. Much
better to me are "morning wood" or the evocative "morning glory," which is the term we used in the (USA) South.
For a funny look at how difficult it is to pee with an
erection, look at the DVD outtakes of Steve Carrel's movie THE FORTY-YEAR-OLD VIRGIN.
