(n) when one pop's a boner at a funeral, or a wake
Damn man, did you see Jimmy's dead grandma?? she gave me mourning wood.
Frank was quite embarrassed when he got mourning wood at his friend Fritz's funeral.
However, he did get some nice winks
from the widow.
When you get an erection due to nostalgic thoughts of an ex-lover.
Dude 1: "Stacy's ass was so nice... I miss it so much..." *pops boner*
Dude 2: "Did you just get mourning wood?!"
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.
