PACE car 

An acronym standing for "Phone, Asian, Chick, Elderly," stereotypically considered the four worst categories of drivers (i.e., people talking on cell phones, people of Asian decent, women and old people). Similar to a pace car in NASCAR, the PACE car usually sets the pace for the flow of traffic by driving slowly or erratically in front of cars wishing to pass or drive faster. Once the PACE car gets out of the way, traffic will return to normal speeds and predictability. Often other drivers in the rear of the pack will guess which category the PACE car driver belongs to before seeing the driver when and if they are finally able to pass.

Be careful honey, it looks like there's a PACE car up ahead creating a bottleneck in the flow of traffic. At first I thought they were looking for an address or parking space but now I can see its just a PACE car. What kind of PACE car do you think it will turn out to be?

Pace Car 

The one car on the highway, typically driven by an elderly person with their mouth hanging open, which pulls into the passing lane, only to remain the same speed as the other cars, thus making it impossible to pass other cars.

Driver: damn, this old lady is clogging the passing lane.

Passenger: chill, there's always gonna be that one the Pace Car

New Mexico Pace Car 

A New Mexico Pace Car is the act of sitting with your buttocks above your head (preferably on a wall at a 45° angle) and pooping onto the front of yourself. The goal of the New Mexico Pace Car is to outrun your excrement before it slides into your mouth using your penis as a shift knob.

Co-Worker 1: "Hey man, what'd you do this weekend?"

Co-Worker 2: "Well, I figured since it was the anniversary of my divorce I'd celebrate by giving myself a New Mexico Pace Car and watching re-runs of M.A.S.H."
