Slumber Lumber

Pre-morning wood.
While still sleeping girlfriend notices you have an erection.

So the other night I unknowingly had sex with my girlfiend with my slumber lumber.

Me - Adam suffers from slumbering lumber even when he isn't drinking.
Jack - He should really see a doctor. They have pills for that now

Slumber lumber is another euphemism for waking up with an erection- otherwise known as 'morning wood'.

"I woke up with some gnarly slumber lumber and I asked if I could take it to her sawmill."

When you take a long nasty shit in your sleep.

I after I finished fucking this chick we went to bed, but then I woke up the next morning and discovered a slumbering lumber.

A more sophisticated version of morning wood. Usually when you are fully asleep, and the blood can add extra power.

Sarah: After Steve fell asleep, he got the most AMAZING slumber lumber last night.
Kiki: Wow, I wish my man, Jamal had that.

Sarah: True Story

She fell asleep on the couch watching full house again! She's in a deep lumber slumber.
