Ebbening - When one guy stands on his back while his buddy stands on hi

When one guy stands on his back while his buddy stands on his feet and dumps a load on him.

My cousin did ebbening at the party and got peed on by his friend. It was epic.

Ebbening is the worst. I tried it and my friend peed on me like I was a toilet.

We did ebbening at school. My friend peed on me and I still have the smell.
