Porcelain horse collar
The sexual act of bending a woman over the toilet and sticking her head through the toilet seat while having doggy-style intercourse, thus creating the illusion of a horse collar.
Dude, I met this freaky chick at the bar last night. I took her home and gave her a porcelain horse collar.

My friend doesn't have a lot of money so he had to get a porcelain horse instead.
