Horse Railing 

You take your bed and push it up against the wall. Then you get on the bed and proceed to jump up and down next to the wall while you smack you dick against the wall repetitively, while still jumping up and down until you come to a climax.

Jacking off has become a thing of the past since my youth pastor taught me the ways of Horse Railing.

Raining horse cocks 

Extremely intense rainfall. The loud noise it makes hitting the roofs of buildings and cars sound like a pile of horse cocks was dumped on it.

Person 1- wow it's really coming down out there.
Person 2- yeah it's raining horse cocks
