One who jams, implodes, shatters, spins, or twist a male's spine during homosexual intercourse. Resulting in the jammie (the one who's spine was deformed) having to use a wheel chair for a year to the rest of his life (depending on the force and intensity of the spine jammer). Could cause the full-body to be paralyzed.

Other male: "No way. I heard your a spine jammer, and i still want to be able to walk."

2-3 men stand on a ladder with a Male or female participant laying at the bottom. The first man shits, then the second, and so on until all logs have been dropped on the participant at the bottom. Some logs will collide causing a jam.
Last week Frank and Eddie told Martha they needed to borrow a ladder for the neighbor so they could fulfill her dream of a Tennessee log jammer.
