When a male takes a random shit in a public area and uses the feces as lubrication to achieve a heavenly orgasm thru aggressive masturbation.

There is a train passenger in San Francisco that takes random shits on buses and masturbates with feces.......
grease railing is a tool used to lubricate the rails of light rail trains.
Little to the bus drivers awareness that the lone passenger was going to achieve grease railing at the last stop!
Get the Grease railing mug.
