look up any word, like blumpkin:
 
1.
Urban public transportation rail passenger car, such as a subway train or light rail train. All, or nearly all, riders are Moolies. Found on hood-to-hood rail lines, or hood-to-downtown lines. Late at night, street people ride Moolieliners to sleep and/or stay warm. Smells like urine, spilled beer, poor personal hygiene.
Suburbanite: "This subway train is disgusting! Trash all over, people drinking malt liquor, smoking weed, eating fried chicken. There's graffiti everywhere, and it stinks!"

City resident: "Motherfucker, you crackers call this 'ridin' da Moolieliner.' "
