A Louisiana doo doo train is when a person eats a big rack of bbq ribs then poops into someone elses butt, then that person poops on the first persons chest.
Its like 2 girls 1 cup but without vomit and you poop in to the persons butthole then get all that poop on your chest thus making it into the Louisiana doo doo train.
