Rail Slide 

When one willing individual snorts a line of cocaine (benzoylmethylecgonine, an ecgonine derivative) off of another man's penis imitating a skateboard grinding or sliding down a hand rail of a set of stairs.

Bro, you were so drunk that you did a rail slide in the men's bathroom. Gat damn.
