look up any word, like lemonparty:
Similar to a Circus Clown Car, except that instead of 15 or 20 clowns packed in a car for amusement. A Mexican Clown Car is packed with 15 or 20 Mexicans illegals trying to cross the border.
Last week a Border Patrol agent pulled over a suspicious vehicle that turned out to be a Mexican Clown Car.
