Driving with an illegal number of passengers. Derived from how media often portrays illegal immigrants crossing the Mexican/American border, with many of them sitting tightly packed in the back of a truck.

Driver: Ready to go? We gotta pick up Joey, Tom, Kelly and Sarah too.
Friend: Doesn't your car only fit four?
Driver: Yah... We're going Mexican, no worries.

Get the going Mexican mug.
the act of three passengers occupying the front bench seats of a truck, even when there are clearly 2-3 more seats in the back.

term is derived from the observation that Mexicans will often all sit in the front with each other, leaving the back seat clearly vacant, probably so one person is not left to be a loner in the back seat.

Nothing against Mexicans, purely observational. I'm Salvadorean, and probably have more Mexican friends than Salvadoreans.

Papa Bear: Nice.
