Waking up with an erection. It's often associated with the need to use the bathroom upon waking up. Scientific term is nocturnal penile tumescence. There is no real scientific proof as to why men wake up with a erection although there are many theories. And by the way "dr. Pascalle" is a fake and an idiot. No such thing as hypervasodilation.

Means the same thing as Morning Glory
It sucks trying to take a piss when you got a morning wood.

When you wake up and you have a massive boner. You could go camping with the tent you pop every morning. You cannot get out of bed untill everyone is out of the room.
When i pop my massive tent, with my morning wood all the girls jumped in.
