Doing a line of blow off of a chick's pubis or right off of her naked snatch.

Grease railing

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!
