Death Caravan 

A vehicle full of rowdy passengers traveling a certain distance to attend a large party.

Often times there are more passengers than seats and people are drinking in the back seat. In an especially rowdy death caravan all 4 tires are flat, pitchforks are hanging out of broken windows and the rear of the vehicle is on fire.

Guy 1: Dude the party tonight is gonna be sweet
Guy 2: Yea and Mark, Steve and Tommy are driving here from Buffalo for it.
Guy 1: I heard they're taking the death caravan
Guy 2: They'll be lucky if they make it here alive

Caravan of Death

In October 1973, Chilean dictator Augusto Pinochet organized the “Caravan of Death," a military death-squad charged with eliminating perceived opponents of the military regime. Flying a cross-country circuit by helicopter, the Caravan of Death landed at military bases throughout the country and tortured and summarily executed at least 75 political prisoners.

Many of the victims of what became known as the "Caravan of Death" had voluntarily turned themselves into the military authorities. Prisoners were taken from their cells and summarily executed, often without the knowledge or consent of the local military authorities.
