When you take a dump, then piss on top and leave it to soak overnight. If the turd is particularly powerful, and the toilet seat is left down, the resulting stench is fucking brutal upon discovery.
This morning I was greeted by a marinated turd when I went into my bathroom.
That bitch pissed me off, so I left a turd marinating in her toilet.
A regular spitroast, but with another male paticipant ejaculating or 'marinating' the lucky lady in the thick of it all. Who wants a spitroast with meat that isn't marinated?!?
'Last night Ted and i were having this awesome spitroast. It was a bit flavourless though so Jim started to marinate the bitch. Best marinated spitroast i've ever had!'
