The juice that lingers under the skin around your balls a long time after having sex with a girl. It usually goes away after showering, but re-surfaces when you sweat again....it can sometimes seem to last for like 2 weeks! For long-lasting effects, fall asleep inside the girl...
"damn Gina, i got marination all over my sac" And it won't go away....
When you marinate meat for such a short length of time that it adds no flavour whatsoever and does nothing for tenderizing the meat. You might as well have rubbed the meat on your balls instead.
"He prematurely marinated the meat, and yielded no flavour or tenderising as a result"
"His meat was flavourless like a bland, prematurely marinated sausage"
"Premature marination is like adding chilli jam to fried rice, it bad and make you stupid"
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.
