An extreme sexual act in which one fills a kiddie-pool with anal lube and then both partners lay in it and "marinate" in the lube for at least 30 minutes. After marinating, the partners engage in a four hour long dirty anal sexual marathon.
The act of staying extremelycomfortable under the duvet in bed. Normally when hungover, or having taken a morning shower and realising one can go back to bed.
"Ah man, my class at 10 was cancelled but I was already up, not really feeling being awake though..."
"That's alright mate, just go back to bed for some marinating!"
