Lay Track 

A sexual move that has yet to be performed or even captured on video.

It involves a man and a woman or another man.

The woman lies on her stomach, with a butt plug in her ass, and the man proceeds to shit up and down her back, preferably using only one log.

"So did you lay track on her?"

"I fucking laid track on that bitch, two full logs."

"...You're a sick fuck"

Lay Tracks 

When you go into a public restroom stall and lay out some smooth sounds... Also known as serious gas farts (also long turds) in the stall.

"I've got to go lay tracks in the sound booth." Also: "Man, I have got to hit the sound booth and lay down some heavy tracks!"
