Shit Train 

The level of inebriation or drug-induced handicap that is far beyond the standard human experience. If the terms "tipsy" and "buzzed" are used to describe the low end of this spectrum then the only level higher than "Shit Train" is death. Subjects designated as Shit Trains are likely in the beginning stages of alcohol poisoning and should seek immediate medical assistance.

"Did you guys ever find Nandini after the club?"
"No, was she ratchet?"
"No girl, she was a Shit Train."
