Dirty Portia 

When you dress up as a horse and stuff bree in to you own anus untill it melts so you can fluctuate bree bubbles whilst masterbating

Person1: why does it stick of cheese.
Person2: oh I had some spare bree and fancied a dirty portia.

Example 2

I was watching the dressage last night with a cheese board and remembered that time I got introduced to a dirty portia.

Dirty Portia 

The act of shitting in someone’s mouth while they sleep and jerking off as they spit it out of their mouth.

Guy 1: “Dude did you just dirty portia me?”

Guy 2: Fap Fap Fap Fap
