Morning wood is an informal term for a morning erection, for which the technical medical term is "nocturnal penile tumescence". It means an erection that a man sometimes has while asleep or right after waking up. Men who do not have erectile dysfunction can experience this sensation. It usually happens during Rapid Eye Movement sleep. Other slang terms include "morning glory" and "morning tent".
