the state of being so drunk you shit your pants.  the shitting usually takes place with underware on, and while laying in a bathtub.  unleashing the a-train usually happens after taking a-bombers.
dam man jimmy took 3 a-bombers, 11 beers, and a couple rips pff the bong and then didnt have a choice but to have the inner a-train come out.
