Turdbarfing 

When you take a poo in the toilet then turn around and puke on top of it.

"I was so hammered last night after that huge party, by 3am I barely made it to the head and ended up turdbarfing.

Turdsurfing 

The act of using a mobile device for internet access whilst using the toilet. For example, use of an iPhone for web access while using the toilet would constitute turdsurfing.

Today I had a good turdsurfing session.
