the expression of deep sorrow for someone who has passed, shown by having a boner
My grandma’s funeral was so awkaward. I stood up to speak out about her life but I was sporting some rowdy mourning wood. I was rock hard.

n- when one wakes to find he has morning wood, but also has to urinate so bad it hurts.
I was so happy when I woke up with morning wood, but then I realized I had to piss, my morning wood had turned into mourning wood.

It's akin to the more widespread 'morning wood', but instead of being a function of a typical male, it is instead a daily reminder to necrophiliacs. It does involve an erection upon regaining consciousness, but instead of being caused by lustful porn stars, it's caused by sadness that your lover last night is now six feet under, and you are depressed, but more so you are excited at the thought of having them once. Hence the title 'mourning wood'
Doug: Hey man, that party we had at the cemetery last night was a blast.

Mike: Yeah, i found a 40-something blond amongst the oldies. I definitely had some mourning wood when i woke up.
