A phrase coined following the events that transpired between the members of the 1988 Jamaican bobsled team in a Calgary hotel room. An act in which four men, of Jamaican heritage, run a train on one another, leaving one man, known as the engineer, at the front of the train guiding the man-sled.
My girl and I just watched Disney's 1993 hit Cool Runnings and now she wants to try a Jamaican Meat Train (JMT) together, but I don't have the heart to tell her she'll have to watch.

Steve: “Hell yeah!”

Example 2
