Beijing Horseshoe

A sexual position involving several brothers standing in a semi-circle around a horse, (or in extreme cases, a human pretending the role as a horse, although that is less common) and ejaculate on the horse in unison until it is soaked.

"I'm really proud of my first Beijing Horseshoe! We Beijing Horseshoe'd the shit out of that horse!"
"Oh cool, but you say 'we' who did you do it with?"
"My brothers of course, why else would i say that i did a Bejing Horseshoe?"
