i shit trains

To shit trains typically means you are the shit. It can also correlate to being number one at everything. Often times used for upping a Mister One Upper, or someone who has to beat you at every event, activity, or story you've ever encountered.

I Shit Trains!

The act of shitting out a train by the power of Unknown forces.

The cops was about to get my ass so I yelled, "I Shit Trains!" And by the power of the Unknown I shat a train that derailed another train and killed dem.
