J-Train

When a crackhead rides on the train with you. As soon as he rides, it automatically becomes a J-Train.

hey man, I was taking the Metro line in L.A. and some crackhead hopped on and before I knew it, I was on the J-Train.

J Train

A subway line from the NYC Subway System that is very slow, horrible service, and has filthy subway cars.

The J Train always has crackheads on the trains and service always backs up.
