A morning erection that is naturally caused as the brains enters the REM-deep sleep phase. At this stage, the body's skeletal muscle structure relaxes and causes hypervasodilation in the capillaries of the body, resulting in said erection.
After sleeping so soundly and having a great night's rest, it is no surprise to wake up with an erection.

Perhaps one of the greatest of God's creations, but at the same time the worst. It all depends on the circumstances. When the body goes into REM sleep, capillaries go into hyper vasodilation, and thus the penis becomes goes in one of the most intense and hardest erections a man can experience.
TEACHER: Tommy!? You're late again! Care to explain!?
TOMMY: You want the truth?
TEACHER: Yes!
TOMMY: OK, here it goes. For the past few mornings, I've woken up with some gnarly morning wood, and to waste something is a sin; so, I took full advantage of the situation each time.
DAN: Dude, what's up? You sick or something?
JAKE: No, man. I slept naked last night, and slept in this morning to the point where my mom came into my room and threw the sheets off of me. I had massive morning wood, dude, and she saw it. AWKWARD!!!

when you wake up in the morning with an erection. is exceptionally poor if you are wearing gym shorts, because you usually have to stay in bed for a few minutes while it goes down if you have other people in your house, and generally sticks straight out, not following up your body like normal wood.
i couldnt get out of bed for a few minutes this morning because i had morning wood and it wouldnt go down

When you get a NARB (no apparent reason boner) after waking up, usually caused by a full bladder pressing against the prostate.
