Banging a girl from behind while she vomits into a toilet. Best used when said girl is completely hammered.
I gave Cally the Porcelain Cowboy last night. She was so trashed. I was like 'Yippee Ki-ah mother fucker! *smack*'

Similar to the standard Porcelain Cowboy only you are slamming the drunk/puking chick in the ass while her head is hovering above the toilet.
Kari was hammered and had to puke. I helped her to the washroom like a gentleman but couldn't resist sliding in that ass that was just staring at me while she was bent over hurling. She seemed to be really digging it until the dry heaves started. I almost popped out a couple times during that but stayed on for the 8 count . It was the 1st time either of us had pulled off the Dirty Porcelain Cowboy
