A recreational pastime involving drug-induced positioning of one's body directly underneath the rail supports of a railroad trestle, exactly timed to coincide with the passing of a freight train overhead.
The resulting effect is that of experiencing a passing freight train from a position a foot or two beneath the rails upon which the train passes. The resulting vibration and noise is traditionally enjoyed during night-time while under the effect of psychodelic mushrooms or other hallucinogen. As the train approaches, the increasing noise and vibration, coinciding with the shifting headlights and roar of the train whistle adds to the effect. Other variants include hanging by the hands from individual railroad ties while the train passes.
So dude, we went out towards Lexington on FM 969 with our nine-irons and some golf balls, picked some shrooms, knocked 'em back with a bottle of Ranch dressing, then when our gums were tingling good we went out trestling at Five Mile. It was a wicked rush!
