4.
n. also piss hard; an erection induced by a need to empty the bladder upon awakening, with flaccidity returning as the bladder is drained. Wanking a piss hard-on produces no pleasure.
Tyrone awoke with a tentpole erection, but realized his piss hard was simply a need to relieve himself and not penetrate Brie Ann again.

1.
Morning erection or hard-on combined with a need to urinate. The need to drain the lizard is not, in reality, the cause of the phenomenon.
I woke up with a piss hard-on, so I went out to the balcony of our hotel room, took a leak into the pool below, went back into the room and started to do her through the back door before she even was awake

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.

that erection you have when you first wake up; due to the accumulation of urine over the night. It is especially hard and stiff, the best kind to fuck with. In a pinch, it is a great towel rack! Even if you hang a wet towel on it, it will stay hard as hell! A great, if slow, fuck cock. Girls love it!
man: Oh, Baby, look at my piss hard on!

wo-man: Oh, man, that needs to be in my pussy!

man: Should I piss... Or should I fuck?

wo-man: Fuck me, baby, fuck me!
