- A pass thrown from one shoulder to the same shoulder of another juggler, when they are facing each other. That is, a pass thrown from the right hand to the right shoulder, or from the left hand to the left shoulder.
Picture a rectangle (or parallelogram, for feed patterns, etc.) connecting the two jugglers, with the shoulders of the jugglers being the corners of the box. Tramline (and self) passes go along the sides of the box, diagonal passes cross through the box to the opposite corner.
